Another video I have been looking for! This is also on the list due to my s38 swap, didn’t think the clio boosters were as available as they used to be. Great information too, you really do put some effort into these vids!
Couldn't even find a decent pic of the correct Clio booster 😆 Someone else in the comments mentioned that having tried both, the E90 booster gives much better feel. Looking forward to feeling it. Hope the vid helps you along with the build mate!
Cheers pal! 😃You can never have enough tools. Every job I do it seems I'm missing something. Probably why the collection has grown so much. 😆 Most of them are hand-me-downs from the old man to be fair though.
Thanks mate! Yeah, there's plenty of difficulties whichever servo swap you do. But not being able to find a Clio one made the choice a lot easier for me. 😂 They seem like very rare things these days.
And yet another great video! I have been working for more then 25years on different E30's , and still doing this. Love to see your progress , you should have way more followers! Cant wait till the next one
Thanks so much Frank! 😃 You must've built up a wealth of E30 knowledge and experience with that many years under your belt! I'm still figuring things out as I go. 😁
@SPANNERRASH and all - Another Tip that the lad at the scrapyard told me is that pre facelift E90s didn't have the Booster Vacuum Sensor, I got that one and seems like I wouldn't need to block that off. Haven't done it yet so not sure if anything else is different :) Great Guide as always!!!
Ahh yes somebody else mentioned about that additional port. I thought all E90's had it but evidently not. Finding one without will save you sourcing a bung. 😃 Cheers!
Ευχαριστώ πολύ, όλα σου τα βίντεο είναι αναλυτικά και η αλλαγή κινητήρα σε Μ52 που εδώ στην Ελλάδα είναι πολύ δύσκολη, με τα βίντεο σου πιστεύω πως θα την κάνω την μετατροπή. Το δικό μου ήταν Μ40 316i 1990 το μετέτρεψα το 2015 εγώ σε 318is και τώρα θέλω να το μετατρέψω σε M52. Ευχαριστώ.
Ακούγεται ότι το αυτοκίνητό σας ήταν αρχικά σαν το δικό μου. Χαίρομαι πολύ που τα βίντεο είναι χρήσιμα για εσάς. Μου άρεσε να έχω ένα E30 318 πριν από χρόνια, ελπίζοντας ότι το M52 E30 θα είναι το επόμενο επίπεδο από αυτό όσον αφορά τη διασκέδαση. 😃
Very very clean install 😊 Love it. Better than my installation on the lines. But mine is ABS, so had to custom it. Small heads up, on the servo matting side, try to apply some sealant or gasket, this has a purpose of not letting water in and movement of the firewall against the servo. Can have some creaking noise due to only 2 bolts. Oh, another tip, F10 brake reservoir sits in very well and looks like factory fitted. Clears the throttle body of the M52.
Thanks Felix, yeah I thought ABS would make life a bit more awkward so I'm lucky I guess. The E90 booster did actually come with a little foam gasket which I made sure to put on, hopefully that prevents any creaking etc. Would the F10 reservoir fit with an M50 intake manifold too? I'm debating trying one out when the engine is in. 😄
nice work. i would make a bracket to pick-up on the reservoirs mounting holes. Maybe drop it down to pick up on the master cylinder/servo mounting studs directly below?
Thanks Martin, yeah I plan to do pretty much exactly that. No doubt there will be a lot of refining to do to this E30 once it's all back together. I'll be keen to get things like that resolved once it's a car again.
just had a look at the Z3 braking system diagram...they are all M10s at the calipers but when you get to the unions on the ASC module, it's M12 nearside and M10 offside
Big thank you for the video on the topic. I use E60 booster with E34 rubber mounts and this brake fluid reservoir (03.3508-5851.3) exactly the same as in the video but with an added port for the clutch.
Indeed your have eared my great respect!! Your videos are IDEAL for e30 fanatics!! Great analysis in terms of technical issues, as well as PERFECT sound quality!! Thanks mate and many thanks frankly!!!
Great video! I too was dreading the part where I would have to weld the E30 clevis onto the E9X booster but I found out just as you did that there was no need to do so. I used a longer clevis pin in mine which I handily had in a box of bits. Another thing to note is that there is a E9X booster which only has one vacuum port. When I bought mine off eBay I had to double check the pics of the actual part to make sure it only had one port.
Thanks mate! Ahh I didn't know one existed without the additional port, that's good to know, thanks for sharing that, it could help someone select theirs better. I hadn't even thought about that until I got the booster to be honest. For once I think RHD have an easier time with this one. Normally it's just extra complication.
Forgot to mention the braking feel of this booster compared to a clio booster is absolutely superb, it’s a night and day difference when compared to the clio one. I found the clio booster gave me very wooden brakes that did nothing until they would lock up suddenly with very little braking feel at the pedal. The E9X booster gives a very nice pedal feel and you can feel the brakes coming on progressively and no locking up. I’m sure you will be very happy with this setup when it’s all up and running, I definitely was with mine.
@@ajbrar6554 Oh wow, well it sounds like I've done the right thing going this route then! Can't wait to see how it all feels when used in anger. Cheers!
Such good info in here thank you mate, i would have definitely welded the E30 pin on, at least with this info i can knock up a new pin and some spacers on the lathe to get the job done.
I was bloody certain I'd need to weld the E30 clevis onto it. Everything I'd read said so. Glad I offered it up to the car and checked before getting handy with the angle grinder. 😆 Hope the vid helps you out with yours!
Thanks John, hopefully it fits like I expect it to! 🤞 Good question on the fastener holes, I'm considering a little bracket to secure it to the booster and use them. While I'm sure it's not going anywhere, because it only connects via push-fit with the 2 tubes, it doesn't feel as solidly on there as the one I removed did. Not helped by it being taller either. So I'm considering that more than chopping them off.
Very useful video - thanks. As a suggestion: Autodoc are offering significantly better prices and lead-times on the BMW 2002 reservoir and grommets than the Latvian site suggested
In mine i have put in from golf mk1 series didnt touch anythin even the rod for the pedal is exact replacement and have no problem years now. I used the original e30 pump
Very true, could have just done an M12 fitting for the fronts between it and the T-piece. But I didn't have any M12 fittings, and I'd still need the adapter for the rear. There are a few ways to skin a cat, but I think this arrangement worked out pretty well. 😁

Almost certainly not, but I've also switched the calipers so that was already out the window. 😆 I suspect the front/rear ratio will still be good but I will hopefully find out very soon!

Turned out to be such a relatively easy swap! Nice one. Not sure but doesnt the pin need to sit more firm? In the e30 it can't move if i'm not mistaking. Maybe add some extra spacers ? Guess the pin could wear over time when it's able to move. Or i'm just being too precise, thats also a possibility 😂 can't wait for the engine fitment. What are your plans with the engine on the channel? Gonna rebuild it first ?
Took me a while to figure it out if I'm being honest! 🤭 I think the pin is spot on, sure there's no play in the E30's clevis/pin but seems to be like as long as it's kept around central, which the spacers solve, there's nothing really to go wrong with it. I think the extra wear will be a long way into the future but, interesting point. Maybe I'll grease it every so often. 😆 Going to give the M52B28 engine a good check over and unless I see something that warrants a rebuild I'm just going to send it. I'll have to tidy it up a bit first though, it can't look scruffy in my shiny engine bay. I can always rebuild it in the future, but I'm dying to get this car moving under its own power again ASAP. Fingers crossed I can proceed with the plan and don't find anything wrong with it. 🤞
Awesome series dude! Me and my dad are following along, M52B28 into a 316i. We've gone for the same E9X booster you've done but the pedal doesn't return? Not sure if you or anyone watching encountered this?
That's amazing that you're working on pretty much the same build with your dad too. 😆 I hope the project is going well, the brake pedal with the E90 booster feels really great so far, feels totally normal and returns. Check your linkage I reckon, maybe its catching on something.
@@SPANNERRASH thanks dude! MOT booked now 🤞. We've sussed the brake issue, where my 30 has ABS you need to adjust the pedal so that the linkage lines up. There's a nut behind the pedal on the linkage that allows for adjustment. Hopefully someone finds it helpful.
The one which connects to the intake manifold? I think I covered that in a later video, the one where I fit the M50 intake manifold. However, I can tell you I used an off-cut of PAS line. A very sturdy line. It's strongly advised that you use a reinforced and/or steel braided line for this. If it's a soft line and it collapses, you will lose braking force and it could end in disaster. Definitely don't run one with a kink in it.
@@SPANNERRASH Thanks man, i done the e90 booster swap already and just finished the mondeo mk3 caliper upgrade. But not 100% happy yet 😂 will try replacing the pipe 👊🏽

@@SPANNERRASH I was referring to the intake manifold, I already installed the e90 brake pump and I have a problem with the installation of the intake manifold
@@rodrigotv9934 Ah check out my later video about installing the larger M50 manifold. It's tight but with a little trim of the fins on the manifold it fits perfect! You will see 😃
Bok, na E30 s volanom na desnoj strani kao što je moj, kvačilo ima poseban spremnik na suprotnoj strani odjeljka motora tako da to nije problem. Za model s volanom na lijevoj strani, možete dobiti isti tip rezervoara iz 2002., ali s dodatnim otvorom za vod spojke. Mislim da sam to spomenuo u videu. Nadam se da pomaže! 😁
@@SPANNERRASH yes and the E30 top fits the E60 reservoir as well, you don't even have to change the grommets to fit it on top of the brake cylinder. But I think it depends on the intake manifold and how much space you have, it seems to work well with M50 swaps
LHD and RHD E30's have the brake master cylinder in the same place. Just RHD cars have a linkage inside the cabin. However E90's are sided. LHD E90s have the master cylinder ports on the booster on the wrong side for the E30, so pick up a RHD E90 brake servo and you will have a better time. 😃
Here's the info for the booster I got: BMW 3 Series E90 E91 E92 E93 LCI Brake Servo Unit Master Cylinder 6788040 (UK market, RHD). OEM part no.: 34336779721 34336785665 34326764117 6788040 Hope that helps!
Interesting question, sadly though I'm pretty sure the answer is no. The studs that fasten on the master cylinder to the E90 booster are nowhere near the ones on an E30 MC. I can't think of a way to make it work without some kind of adapter, which would definitely be harder to make than messing with the lines! 😄
@@SPANNERRASH that is good to know, might give it a try making the hard lines then. I wanted to do some sort of upgrade to my brakes but not sure what yet, might just go for harder pad better discs and braided lines. I want to turbo my m20 might be enough stopping power anyway
@@Dsilveiro by all accounts this E90 booster should make the brakes feel a bit keener than the stock E30 one. But I reckon you're right about trying the others first. A quality set of pads and discs could transform the initial bite, and some quality fluid could help reduce fade from repeated stops. Of course, if the soft lines are original they might be bulging under hard pedal stomping, so switching them for braided sounds good too. Bear in mind though, the tyres will probably have the biggest impact when it comes down to stopping distance, especially if you've no ABS like me! 😆
@@Graham.-E30 Cant remember it if I'm being honest. This one looks spot on though: ebay.us/TopN1v I doubt the auto ones are any different, but I'd hate to be wrong about that. If you pick one with only one vacuum hole though you won't have to plug the second. 👍
Great question! I think yes, but having never done an M60 swap I can't say for sure. Hopefully someone with the knowledge can chime in and answer that here for you. 🤞
There is simply no room for it on the bulkhead with a V8 so are 3 options. 1) run it booster-less via a pedal box 2) use the E34 style remote booster mounted behind headlight. Some adaption of factory brackets and frame rail required. 3) locate inside the car in the glove box area at a 90deg angle. The latter of which I chose to do for my E30 M60. (Long term project) 😅
it is indeed proportional valve. but i have mine removed completely. i have 1to1 same vuild as yours, and i was worried that removing it from the game will make it lock the rears. however already 2t km on ODO and everything brakes as a charm. no sign of rear over braking.
Aha!! Thank you for clarifying that, I thought it might be. I might try removing mine at some point too and see what the effect is, I guess no effect in your experience. 😄
@@SPANNERRASH you actually can remove straight away. as later it will be pia to reach it there. main differense is that original e30 brake master had equal size out-ports for front and rear + you (as i :) ) had drum rear brakes, so therefore pressure going to the rear and the front was equal, however braking effeciency of drum rear and disk front brakes was different. so thats where proportioning valve comes in play. however in newer e90 beake master cylinder you can see the diameter of the front and rear outgoing ports stamped on the body of master cylinder. and main thing that they are different from the factory 👌
@@Johnson26905 I see, that makes sense! Well that's really typical as I do want to remove it now, but since filming I decided to go ahead and bleed the brakes back up! I think I'll save removing it for a later date because I absolutely hate getting brake fluid everywhere. 😆 But now its definitely on my list, thank you for enlightening me on that!
@@drayescobar9469 One port is simpler, it will be ideal. The ABS model E30 will be much the same. The only difference is that the lines will go from the master cylinder to the brakes via the ABS, rather than directly. I think when you lift the bonnet and trace the lines that will become much more obvious to you.

If it's a soft line and it collapses, you will lose braking force and it could end in disaster. Definitely don't run one with a kink in it.
@@SPANNERRASH Thanks man, i done the e90 booster swap already and just finished the mondeo mk3 caliper upgrade. But not 100% happy yet 😂 will try replacing the pipe 👊🏽
@@e30hope No worries mate, glad to help. Mondeo caliper upgrade sounds interesting I will look that up.
The vice is bolted to the bench!
Finally! Works a lot better bolted down too, it was driving me mad. 😂

How much longer is the e90 servo over the e30 one?
A fair amount but to be honest I don't think I measured it in that direction, didn't really see the need. Howcome?
Hello! Do you need anything else to put the admission multiple?
Hi Rodrigo, not sure I totally understand your question, but this setup worked great for me and I left no steps out of the guide.
@@SPANNERRASH I was referring to the intake manifold, I already installed the e90 brake pump and I have a problem with the installation of the intake manifold
@@rodrigotv9934 Ah check out my later video about installing the larger M50 manifold. It's tight but with a little trim of the fins on the manifold it fits perfect! You will see 😃
@@SPANNERRASH Thanks Bro! 🤙🏻
Pozdrav sta uraditi sa kvacilom?
Kako njega povezati na posudu od kočione tekućine?
Bok, na E30 s volanom na desnoj strani kao što je moj, kvačilo ima poseban spremnik na suprotnoj strani odjeljka motora tako da to nije problem.
Za model s volanom na lijevoj strani, možete dobiti isti tip rezervoara iz 2002., ali s dodatnim otvorom za vod spojke. Mislim da sam to spomenuo u videu.
Nadam se da pomaže! 😁
I have seen people using the e60 reservoir because it is smaller than the e90 reservoir and does not sit at an angle in the car. I will try this soon
Interesting, I'll look that up. The 2002 resevoir does seem to be a very good solution, especially using the E30 top for the level sensor.
@@SPANNERRASH yes and the E30 top fits the E60 reservoir as well, you don't even have to change the grommets to fit it on top of the brake cylinder. But I think it depends on the intake manifold and how much space you have, it seems to work well with M50 swaps
@@Valnar1512 It sounds very interesting then, thank you for sharing the knowledge on that!
Is it better to use a rhd master brake cilinder for a LHD E30?
LHD and RHD E30's have the brake master cylinder in the same place. Just RHD cars have a linkage inside the cabin.
However E90's are sided. LHD E90s have the master cylinder ports on the booster on the wrong side for the E30, so pick up a RHD E90 brake servo and you will have a better time. 😃
@@SPANNERRASHThanks for your prompt reply and confirmation.
@@SPANNERRASHanother questions, is there a difference in the brakebooster itself, between lhd and rhd?
what's the part number from the servo?
Here's the info for the booster I got:
BMW 3 Series E90 E91 E92 E93 LCI Brake Servo Unit Master Cylinder 6788040 (UK market, RHD).
OEM part no.: 34336779721 34336785665 34326764117 6788040
Hope that helps!
Hi, would the e90 booster work with e30 master cylinder? Don’t really want to play with hard lines
Interesting question, sadly though I'm pretty sure the answer is no.
The studs that fasten on the master cylinder to the E90 booster are nowhere near the ones on an E30 MC.
I can't think of a way to make it work without some kind of adapter, which would definitely be harder to make than messing with the lines! 😄
@@SPANNERRASH that is good to know, might give it a try making the hard lines then. I wanted to do some sort of upgrade to my brakes but not sure what yet, might just go for harder pad better discs and braided lines. I want to turbo my m20 might be enough stopping power anyway
@@Dsilveiro by all accounts this E90 booster should make the brakes feel a bit keener than the stock E30 one. But I reckon you're right about trying the others first.
A quality set of pads and discs could transform the initial bite, and some quality fluid could help reduce fade from repeated stops.
Of course, if the soft lines are original they might be bulging under hard pedal stomping, so switching them for braided sounds good too.
Bear in mind though, the tyres will probably have the biggest impact when it comes down to stopping distance, especially if you've no ABS like me! 😆
@SPANNERRASH I do have ABS and brand new tyres, always wanted wilwood 4pot but maybe don't need that much stopping power
Thank you for a very informative video. You’ve gained a subscriber 😊
Would a brake booster from an e90 automatic be the same
I certainly think so, but I'm not 100% sure about that so worth researching.
@@SPANNERRASH do you have the part number you used please
@@Graham.-E30 Cant remember it if I'm being honest. This one looks spot on though: ebay.us/TopN1v
I doubt the auto ones are any different, but I'd hate to be wrong about that.
If you pick one with only one vacuum hole though you won't have to plug the second. 👍
Would the E90 brake booster fit with a M60 V8 swap?
Great question! I think yes, but having never done an M60 swap I can't say for sure.
Hopefully someone with the knowledge can chime in and answer that here for you. 🤞
Pretty certain you need to do the relocation into the glovebox, there are kits out there to do this!
There is simply no room for it on the bulkhead with a V8 so are 3 options.
1) run it booster-less via a pedal box
2) use the E34 style remote booster mounted behind headlight. Some adaption of factory brackets and frame rail required.
3) locate inside the car in the glove box area at a 90deg angle.
The latter of which I chose to do for my E30 M60. (Long term project) 😅
it is indeed proportional valve. but i have mine removed completely. i have 1to1 same vuild as yours, and i was worried that removing it from the game will make it lock the rears. however already 2t km on ODO and everything brakes as a charm. no sign of rear over braking.
Aha!! Thank you for clarifying that, I thought it might be. I might try removing mine at some point too and see what the effect is, I guess no effect in your experience. 😄
@@SPANNERRASH you actually can remove straight away. as later it will be pia to reach it there. main differense is that original e30 brake master had equal size out-ports for front and rear + you (as i :) ) had drum rear brakes, so therefore pressure going to the rear and the front was equal, however braking effeciency of drum rear and disk front brakes was different. so thats where proportioning valve comes in play.
however in newer e90 beake master cylinder you can see the diameter of the front and rear outgoing ports stamped on the body of master cylinder. and main thing that they are different from the factory 👌
@@Johnson26905 I see, that makes sense! Well that's really typical as I do want to remove it now, but since filming I decided to go ahead and bleed the brakes back up!
I think I'll save removing it for a later date because I absolutely hate getting brake fluid everywhere. 😆
But now its definitely on my list, thank you for enlightening me on that!
You could also replace it with an adjustable one
@@mcjjordan Good thought!
What year e90 booster did you need?
Earlier ones come without that second vacuum hole, so if you want an easier time go with one of those.
@@SPANNERRASH i found one with only one port, can that work?
@@SPANNERRASH also my vehicle is a 1990 320i came with abs module would the install be any different
@@drayescobar9469 One port is simpler, it will be ideal. The ABS model E30 will be much the same. The only difference is that the lines will go from the master cylinder to the brakes via the ABS, rather than directly. I think when you lift the bonnet and trace the lines that will become much more obvious to you.
