4 Wheel Disc Brake Conversion for GM Muscle Cars on a Budget | 1971 GTO Brake Swap Explained
HTML-код
- Опубликовано: 17 июл 2024
- This time on SPPTV Rob explains how he swapped 4 wheel disc brakes on to his 1971 Pontiac GTO, but this same mod can be done on many other GM muscle cars from that era. Rob lists off a number of models that use the same brake setup as the GTO in the video, but always best to research for yourself.
A 4 wheel disc brake conversion is a common upgrade when getting old cars and trucks back on the road. Often what is currently on the vehicle for brakes needs replacing, and you may as well bring the stopping power of your precious project car up to 2019 standards.
We made a previous video about Rob's S-10 big brake upgrade here...

Jon is a cool dude to hang with. I did a roadtrip in his 75 firebird with him and he helped me with my 68 firebird too. I have the c4 rotor c5 caliper combo on my 68 firebird. Got a c5 setup on my 67 tempest and we have stock gm disc brakes on our 66 buick... it was only 239 for the buick and fit under a 15 inch wheel.
Great video btw
I've been watching you guys for the last 3 years love the content. This is a good stuff why I love watching it because the interchange used parts it helps a lot for the budget-friendly car enthusiasts. Especially when you're trying to raise a family but still love that hot rod life
Thanks for watching!
I'm using the same brakes on my Vega. I have the backs on...collecting parts for the front. Great job...MORE GTO VIDEOS
My 66 Impala uses 11" A-Body Chevelle disc brakes and calipers with the original Impala drum spindles and a simple custom bracket to mount the caliper. Only physical mod was to redrill the spindle for the bearing cotter pin. Used a heavy duty 70s half-ton truck master cylinder, a dual action 8" MasterPower booster and a quality wildwood proportioning valve. Went through 4 cheap repo Chinese valves before going with the wildwood. My 66 B-body is the same weight as a 70 Chevelle so there is no worry using the 11 inch discs. Plus it allows me to still use 14" skinnies up front when I go to the drag strip
Interesting I have a 69 impala and I used spindles and hubs off a c3. Then bought pads rotors and calipers. Gives me 4 piston brakes but they don’t clear 14s or some 15 do and some don’t
Glad you guys like em. They make tool boxes and coffee mugs better, and installation isn't tricky!
Great info, thanks Rob. 👍🏻
Very good info thanks for sharing. EIGHT HOURS MIKE!
Good info! Thanks champ
Good stuff, very interesting
Thanks . Have to do on my GTO.
this just saved me so much time and money to convert my drums on my lemans! thanks!!
Where did you get the bracket
Love that GTO.👍
the GTO IS LOOKING GOOD ROB...
10:37 - Edelbrock shocks, those are collectors items these days. Still have a pair on my ride too from back in 2004.
Rob we need to see more of under the GTO she looks good !
Love the White Castle shirt! lol
I did fbody conversion on my 70 chevelle. Have oem 11” booster . So all I need is 76 corvette master cylinder linked up to my booster to make it work good ? Have a part number for the adjustable proportioning valve ?
Is there any guidance you can lend on the brake lines ? Can I just order a kit off inline tube or summit and use them? Would they need different fittings ? Could you maybe do a breakdown on the brake line set up
I have everything for ls1 conversion but I’m kinda lost as to adapting the lines snd all
I like bigger brakes as well but I just really wanted to go old school period correct 15 inch wheels on my 66 Special and 67 cutlass. So had to go with original disks. . Big brake swaps would work with those wheels😞
those brakes can be found on any 98-02 F body(Firebird or Camaro) they all have the same brakes, even the v6 cars
I put rear disc brakes on my 70 lemans sport convertible back in the late 80s early 90s. The disc bakes came off of a 79 trans am.
What is a garaj?
What,did you use to connect the brake hoses ?
Would this be compatible for 2" drop? The 2" drop spindles say that they have to be disc brakes (I believe).
Is your car dropped or is it stick height?
I saw 2020 camaro ss front brakes for sale and would like to put these on my 70 Lemans
This is the c4 non hd calipers with the 12” front rotors, if you wanted to you could upgrade to the c4 HD calipers you get a much thicker rotor and a 13” dia rotor and for the back you could get the 89-97 caliper off camaros to match the c4 fronts I believe c4 vettes also used the same rear caliper .
Did u need any spacers for the bolt in axles rear end?
Did you take out the well to fit a larger tire?
Rob , I have a SS chevelle 64 with a 462 running 9's & when I hit the brakes the wheels stop ! P.S. stock brakes with aluminum drum ......
so on the rear, you switched the L caliper with the R caliper an R caliper with the L caliper right? so the bleeder is at the top?? :P i think that what you were sayin but wanted to clarify for others who might not know about the bleeder needing to be at the top.
Did you custom make the emergency brake bracket 10:25 that attaches to caliper? I know you can't reuse the E-brake bracket from the donor Camaro. Just looking for options for the bracket placement. Nice video!
Yes
@@SPPTVarmy It also looks like you reversed the e-brake drum cylinder so the lever will face away from the caliper. Thats a great idea! I was going to weld a tab to the shock mount to match the direction of the lever. Not anymore. Well done sir and thanks for sharing.
Holy shit..lol..love your T shirt..🍺🤘🍔
Where can. I get the bracket?
Hey rob I know this video is a few days old but will this brake set up allow the fit of 15” wheels?
No
I would just get slotted disk. The drilled one are proned to cracking I'm pretty sure
Nope. Mine are completely worn out and still not a crack.
@@InvincibleExtremes well I'm sure it's depending on driving style. Not saying they all crack but a lot do crack.
Is the rear axle the factory one with bolt in axle shafts?
Yes
I thought it was backward i thought the disc spindle were the short ones and the drum spindle were longer due to having the anchor pin for the brake shoe springs to attach to🤔?
Yes you are right, i noticed that after the video came out.if you use the disc spindle you have to add a spacer.
Ya thought so cause i remember reading that somewhere where they said the drum spindle was longer and needed to be grinded down to match the shorter disc spindle due to having the extra length for the anchor pin bolt well anyway thanks Rob for the reply
Will brakes off of a 98-02 Camaro work on a 67 Special?
They should, there is a few vids on youtube of guys putting those brakes on 60s gtos etc
Thank you sir!
Is that a Pontiac(BOP) rear diff or a GM?
Its a bop
SPPTV what did you have to do to get proper fitment with the bearings?
Garaaagee
12 or 13 ? If you are doing this you better get that part right otherwise because depending on which rotor size you get your wheels might not fit.
First💪💯💪👍
Question so I have a 68 Firebird and I want to convert it to 4 wheel disks it's got the 4 piston front caliper brakes factory all brand new upgraded uh with new calipers So couple of things I wanted to do the Act breaks but the wheels are 15 now they're old style rikens they're pretty cool wheels don't really want to change them because you can't find them in 1617 or bigger is there a conversion kit with the rotors where they would fit with the 15 inch wheels that's one question the other question is the 684 piston caliper front brakes came with a metering valve Which I believe keeps the front desk breaks from lock up does that need to be deleted I found a power break system from a 69 sport Tempest Everything fits it's all on there even the rotors fit except the differences the 69 Tempest has one piston caliper front brakes so though I have the spindles the rotors the brackets complete for that car I didn't go to the 1 piston calipers it still has the factory for pistic helper brakes
