Subaru WRX STI Brake Caliper Rebuild / Perfect Restoration
HTML-код
- Опубликовано: 11 фев 2021
- Welcome to this weeks restoration. This week there has been a slight change of plan, Instead of working on the WRX rear end mechanicals i am going to be restoring a ruined set of Sumitomo rear calipers for my WRX seeing as i have already upgraded the front it would be a shame not to do the rears ( Link here- • Subaru WRX Brake Calip... ) So the plan is to fix the rust, clean up the castings, paint them, rebuild them and fit them to the car so lets crack on with the work.
First things first a visual inspection to check for defects or any major flaws that would render these calipers unsuitable for restoration and im pleased to say they are in good shape apart from being a little seized from sitting around for years.
The first job was to separate the worst caliper that had the piston missing as i couldn't remove it with normal methods so i cracked the bolts and separated the caliper showing me lots of corrosion in the ports so knew the piston would be locked in with corrosion so i knocked it out using a punch through the fluid inlet ports and then removed the pistons from the good caliper using compressed air.
After the pistons were removed i separated the two caliper halves i then headed over to the parts washer to remove years of brake dust, brake fluid and general road grime this step is necessary to prolong the life of the blasting media and stop the blaster from clogging up with lumps of crud.
Once dry the halves were loaded into the blasting cabinet and given a good blasting this removed all rust and corrosion from the surface of the steel and left me with a pristine surface to paint onto.
After blasting i re-assembled the calipers so that i could grind away the rough casting marks left at the factory and smooth the calipers out so they would appear to be one single piece. This worked out successfully and allowed my to go to the next step which was as usual etch priming the surface preparing it for a following coat of high build primer.
The primer was left to cure them was wet flatted to give a flawless surface to apply my basecoat red onto. Once the basecoat was applied i made up some Subaru decals with my plotter and white vinyl and applied them in the appropriate location then gave them a good coat of clear to protect them.
While the clear coat was curing i set about re-plating the bolts as they were still in perfectly good condition all they needed was a little rust removal and a new coating of zinc and clear passivate and they are good for another 20 years at least.
After all that it was simply a case of fitting new pistons and seals and joining the two halves back together with loctite and the correct torque this was verified by using my fully calibrated Snap-On torque wrench.
And there we have it one set of calipers all ready to be fitted and to do some serious braking :)
Which so you prefer the Subaru single pot or the Sumitomo twin pots? Let me know in the comment section.
As always i hope you enjoyed this video and i'll see you again soon with another episode.

Subaru WRX STI Brake Caliper Rebuild / Perfect Restoration 
Авто/Мото
So i get asked on a daily basis when is the ATC project going to be finished? I think this post will answer all of your questions - ruclips.net/user/postUgzESNZREfL30xjQP3F4AaABCQ
I was thinking about painting my own calipers one day. But since I won't rebuild them, most parts would stay on. Would you know how well the seals/other non-metal parts of the caliper fair in an oven at 400F for 30 minutes?
I literally said "wait, hold up" as you grabbed the old crust piston and oring 😂
Me too.... "NOOOO"... ahh, he was just joking.
@@georgegrierson I knew he was joking, but it didn't stop feelings of disbelief and anger inside me! lol
Of course it is a joke..but there är people that do that..he could not do it..thats impossibel in his world.perfect or nothing..
Haha you know what im like i cant resist a well timed joke every now and again, Glad you enjoyed it :)
@@RRCRestoration I'm rebuilding my GF8 and gobsmacked as how Subaru don't have parts and gaskets for this car anymore?...…where are you getting your parts from ?
3k views on a professional restoration, and someone has already given you a thumbs down. They must've really been looking forward to the suspension rebuild.
You can keep the sandblasting segments as long as you want, it's so satisfying to watch.
This is top notch video making. Great lighting, camera angles, editing, use of fast motion, and overall length. It would be good to have a brief explanation of the products used, such as that white powder. Rather than see a hand taking the bottle from the shelf, maybe show the bottle label, to give a better idea what's happening to the bolts. One of the best restoration videos I have ever seen.
The white powder is "DEOX C" and he has previously explained the process of replating in previous videos in this series.
@@TheUb3rN00b wait, what ? He’s already covered plating ? Is it patreon only ? I’ve been waiting for ages , he’s teased us with it once or twice but...
It looks the same as caustic soda. The electrolysis is cool too!
Thank you for posting. I have been stuck watching crappy "restoration" videos for a while now. Perfect job again, as it always is with you.
Thank you for this video -- attempting the very same job soon, upgrading to 2 pot rears with a used set to rebuild. Fronts are fine for now, will go 4 pot when needed. Super inspiring 👍👍👍
Mmm, shiny! You have already done 2 or 3 caliper resto vids, but it still doesn't get old. I'm pretty sure if you did a video on restoring a toilet brush I'd still find it fascinating.
Superb job as ever sir and thanks for sharing it with us.
Always nice to see you in the comment section :) I think this will probably be my last set of calipers i restore on here for a while as it is getting just a tad repetitive, dont want you all thinking im a one trick pony now do i ;) lol... maybe i should restore something totally odd ball like a toilet brush just to mix things up a little haha
The more I watch your show the more I appreciate the work and time you put into it. Thank you. I'll have all of my friends watching your program.
Thank you so much im really glad you enjoy it :)
I Very nearly cried when you nearly put the old pistons and seals in. brilliant
Haha you know i cant resist teasing you guys a little ;) Glad you enjoyed the video.
We nead an indepth video of you plating technique
Project Binky has one.
@Jakub Štěrba Chemical: Citric Acid and water, 24h bath. Electro: sacrifice steel pieces as + and - in water with bicarbonate powder on a car battery and charger for few hours.
Very satisfying to watch. I can watch it over and over again and still be amazed. Great work.
Absolutely blown away by how good they turned out!
When I see the state of them to begin with I thought they wouldn’t be able to be used!
Fantastic video, looking forward to the next one!
Always nice to see you, Really glad you enjoyed the video :)
i started watching you when i found the honda cub you did.. and now a WRX. and one of the best looking ones around.
Dont forget about the Honda TL and the Ducati 600ss restorations i did too ;)
@@RRCRestoration i wait every week for something.. still waiting on the Honda Atc.
your the most profesional mechanic on here...well done !
Thank you so much :)
Next project: sketchy bench grinder restoration!
Like this to disapprove ;)
Add the vice to the mix as well!
I didn’t think so , I love watching you videos can’t wait for the next one
Thank you so much, working on the next one as we speak :)
very cool uncle. the work is relaxed but with satisfying results. plus a place that is always clean so it is pleasing to the eye.from indonesia
Thank you very much :)
Aye, you nearly had me shouting at the screen there, with the old seals and pistons, then I remembered who I was watching!
As ever, you are a craftsman. Beautiful job.
Take care.
Cheers,
Norm.
Hey Norm, Nice to see you. Glad you enjoyed the video :)
Lovely job. Glad you went for red, everyone knows red calipers are worth an extra 10 bhp!
thank you :) Is that 10bhp for the full set or 10 per caliper? just so know what to add to my total when i hit the dyno ;) haha
Haha it's your car, you decide!, 😆
Brave title! The word perfect in RUclips land certainly gets the internet police and scrutineers going but that was indeed a perfect restoration. Well done.
Bloody good job. Fantastic finished product.
Good tip for when you decide to install them and bleed the brakes. After bleeding the brakes, tighten the bleed valve and next is (very important but often forgotten) to blow out any left over brake fluid inside the bleed nipple. Do this by using some compressed air, don’t forget to hold a rag or cloth above it so it doesn’t spray all over the place ;). It’s a good tip because if the brake fluid stays in the nipple and you cap it off afterwards with the rubber cap, it’s going to be able to absorb a bit of moisture from the air etc. And that will eventually corrode the bleeding nipple which can lead to not being able to crack the bleed nipple or even break it, if you understand what I’m trying to say :) It’s a tip I got from my oldest collegue at work (I’m a motorcycle mechanic). Otherwise as always loved the video and keep up this kind of work man, it really is a pleasure to watch!
Hi, thanks for the tip ill be sure to give that a go when i bleed the brakes up :)
I love that I've never seen you break off a bolt. I'm jealous. lol
Always love watching you make and apply new decals man, Ill never get sick of it
My son put me onto your channel, and I love it, am in the process of restoring my bugeye WRX UK 300 right now and it's great to watch how your doing your classic, look forward too the rest 😉👍
Awesome! Thank you glad you are enjoying the project. Good luck with your bugeye :)
Perfect! As always.its every smal detail as do it perfect result..
Thank you so much 😀
A lot of time and patience went into that prep work to achieve stunning results. Nice one
Really good to see Bolts going back clean, coated, greased and lock tighted. Makes me cringe when I see people rustore vehicles putting on new parts without cleaning the bolts (opportunity to visually inspect too).
I is always nice to see a master craftsman doing a bang up job, WELL DONE 👍
Thank you so much :)
looks better then brand new which is no surprise considering I'm watching your video great work 👍
Thank you very much, Glad you enjoyed it :)
Restoration to better than new. Well done!
Every time I get your notification, I drool a little. Love the attention to details. I find your videos soothing and great. keep the good work, my friend.
Thank you very much! :)
Wow
you’re a very talented Craftsman
Brilliant 👏 love to watch you work. Its the highest of quality workmanship. Proper job!!!!
Been really enjoying your videos! I've got an 04 WRX myself and watching your videos I get both inspired and super depressed at the same time, because I don't have anywhere near the skill or tools/space to do the same amazing work you do, still, really enjoyable to watch! Thanks for sharing!
Thank you so much really glad you enjoy my videos, always nice to hear from a fellow Subaru owner :)
Let's "crack on" is my new favorite phrase!👍
Careful you don’t say crack one off 🤔🤦🏼♂️
It's the british version of "go ahead"
Like the "seeyouagainsoon" in the end, also! :-D
Hi RRC Sir , made a nice job of those, you probably know about Goodridge speed bleeders one way check valve in them, crack one open & just keep pumping the brake pedal, great things & not to expensive, don't need a second person to help, hope your well, ATB Wayne.....
Hi Wayne, always nice to see you. I have seen them but never had any experience with them might actually get a set to try them out as it would be very handy not needing help to bleed the brakes.
Absolutely stunning result! You are a man of very many talents!
Thank you very much! :)
Excellent video as always! I never get tired of watching you work! Keep it up, dude! 🤘
Thank you very much :)
Love watching this craftsmanship, every video perfectly done
Thank you so much :)
Another successful restore amazing job my friend congratulations...
Thank you so much 👍 :)
As always, great job. Order, clean and professional approach. Your videos are a pleasure to watch. Greetings.
Thank you very much! :)
Love the videos. Gives me confidence because I’m gonna be doing the exact same thing to my Subaru soon
Said it before but you really do make great Resto videos
I appreciate that! :)
So relaxing to watch. Just what I needed. Thank you.
You’re welcome 😊
As usual brilliant mate!! Looking forward to watching the rest of the series!!
Kept an eye on your channel for a long while. Love all your work, always a perfect job. Keep it coming :)
Thank you very much! :)
Great save on the brakes!
So much love you put on every restoration, every step looks beautiful, its just crazy :3
perfect way to end this crappy week XD
Oh man you got me. Made me sit up in my chair. Nice work, they came out great!
Haha glad you enjoyed my little joke ;) Thanks for watching and commenting.
What a transformation - awesome work 👍🏽🏴
Thank you! Cheers! :)
Amazing, detailed work as always! Looking forward to more!
Thank you! Cheers! :)
Was a bit scared the second you grabbed that crusty old ring, good man you are.
keep it up!
Haha i cant resist a little wind up now and again ;) Glad you enjoyed it
Better and prettier than they were new 👌
Thank you very much :)
I'm happy watching this beautiful work. Against, congratulations.
Thank you so much 😀
always a joy to watch you work my freind
Thank you! Cheers! :)
quality workmanship 👌👌
Thanks 👍 :)
Hey RRC, clicking your fingers while wearing nitrile gloves is a pretty neat trick (at time 19:07).
Love your imaginative camera angles and transitions.
Keep up the good work.
Glad you enjoyed it! :)
Very good Job mate ! I did the same to my BMW caliper a few month before.
New sub here... I'm a Subi fan boy... good to see you restore a nice Subi. You have great attention to detail! Well done, keep it up
Thanks for the sub it means a lot :) Really glad you are enjoying the videos too.
Great job on the brake calipers.
Glad you like them! :)
Brilliant job mate. Too work! Love your channel and the WRX rebuild project. 👍
Awesome, thank you! :)
Better than new!
Congrats.
As usual very interesting and addictive video. Looking good.
Thanks again! :)
Absolutely beautiful work!
Thank you! Cheers! loving your Plok profile pic :)
@@RRCRestoration Thanks! It's a rare surprise to me when someone knows about Plok. =)
BTW I'm extremely envious that you have the resources to take on this project. My wife and I both drive STis (mine is '04, hers is '11 hatch), but a completely restored GC is the holy grail in my eyes. When we move to a house with a bigger garage (and/or workshop) I hope to emulate your work and start building one of my own!
Anyway. Following your restoration project with great interest. Keep up the amazing work!
Impressive transformation as always, top quality work.
Thank you very much! nice to see you again :)
Great job loving the restauration process!
Better than new. They look great. 👍
Thanks 👍
Great job! To protect these even longer from that great paint job you should have your brakes coated in ceramic pro
Nicely done as always.
Thank you! Cheers! always nice to see you.
Great job, im in the middle of striping out and rebuilding my wrx myself! looking forward to seeing how the rear suspension and rear sub frame turns out 👍👍
Well done man excellent refurbishment great watching how you do it true professional
Thanks 👍 Glad you liked it :)
wow, what a good looking set of calipers haha. Thanks for the upload! I can't wait till you upload you getting on that rear-end haha. cheers mate
Absolutely stunning transformation, as usual a totally top job, 👍👍👍👍👍👍
Thanks so much 😊 :)
Loving the Subaru restoration! Would love to see your zinc plating process in more detail you get some amazing results!
Outstanding restoration.
One question, what did the vinyl cutter cut? Is the white sticky material heat resistant? Just curious. Thanks.
Nicely done!
Thank you! Cheers!
Great work, as usual. Keep up the process and we'll keep liking and hitting the thumbs up. Either rebuild your bench grinder, or get another one to rebuild. ;)
Thank you so much really glad you are enjoying my videos :) I wont restore the bench grinder till it gives up the ghost it just keeps on going ang going at this point its like a long term experiment im running on it lol
you are a great man good job
And that is a like from me.. Great work and fantastic camera work..
Thank you so much 😀
Excellent, as always! Looking a lot less like a Really Rusty Car!
Thank you :)
Outstanding work, good one on the old pistons, lol. Making me think of things to do this summer.
Great video!
My next project!
Excellent work good sir!
Thank you! Cheers!
Great resto mate. :)
Thank you very much, Nice to see you again :)
Unreal work as always chap🤌
Much appreciated thank you :)
Splendid job!
Thank you :)
I'm rebuilding the front calipers on an sv650s and I used the air trick to get the pistons out and they were a lot more violent and louder than that. Gave me a good scare lol.
Nice job! I am sure the red color added at least 10 - 20 hp to the car.
looks like straight out the factory but better..until next time,all the best stay safe bud............dougie
Nice to see you , Glad you enjoyed this episode :)
Great job as always and good to see scetchy grinder making an appearance! I'd recommend investing in the m12 milwaukee angled die grinder and get all the roloc attachments via eBay, aliexpress etc.. For your kind of projects it would be a god send as it was for me doing similar jobs
I'll look into that thanks for the tip always love checking out new tools :)
For some reason, I always thought you had to give a light hone to the cylinder, after bead blasting it. The end result looks light years better than what you started with!
I thought so too, when I’ve restored calipers I didn’t blast the insides, but these may have had corrosion to a point where it was needed
Also guys it's not bead blasting which could pockmark the cylinder walls..even at relatively low air pressure..he usually uses fine ground walnut shell..which is softer than alloy as it's organic material..but particles are sharp enough to remove most surface corrosion..now we know where the shells go when we eat prepacked walnut halves from the supermarket..at least i eat them occasionally or in mixed nuts..
@@markianclark9645 Regardless of the material used (which wasn't the point of my post), my ASSumption was that the hone was necessary, in order to assure a good sealing surface, that's all.
@@American_JeeperI can’t think of any reason to hone the caliper cylinder.
They can require cleaning to remove high spots.
The cylinder bore doesn’t seal the piston, the square cut seal does that, and it should be the only thing in contact with the piston inside the bore.
You would hone an engine cylinder, yes, so maybe that’s where you heard it?
@@Ally.MacMillan No. As it was taught to me by old hot rodders, the reason for honing the bore cylinder of the caliper is to ensure that there is nothing protruding from the walls of the bore cylinder which could make contact with the piston which, over time, could lead to a piston catching on the wall and sticking.
Im sure youre already aware but youll need either adaptors or later model GD wrx hubs to bolt those on. They have a different mount spacing compared to the single piston rear calipers
Hi, Yeah i know about the adaptors i have a pair ordered ;) Thanks for the comment though as that would be very helpful info if i hadn't already done my homework lol
Fantastic work as per!
Thank you! Cheers! :)
Nice work! Better than new!
Thank you :)
I have to get my parts from overseas.....yours look like they washed up on the beach. :)
Another splendid rescue.
Haha you'd defo think so with he amount of corrosion and silt i found inside them, Glad you enjoyed the video :)
@@RRCRestoration you certainly seem to have a salt lover up there on the country councils road team!
Fantastic. Really enjoyable and informative. Would it be possible when you're painting to show a little bit at normal speed? So we can see how fast or slow to move the paint gun around the project? I'm restoring the calipers from my motor bike soon and this was brilliant. 👍
Thank you, glad you enjoy my work. ill do my best to try and slow the painting sections down a touch in the edit;
Top work as usual!
Thank you! Cheers! :)
