GBody Rear Disc Brake UPGRADE!! | Junkyard parts only |  

I’m doing the same exact thing to my 78 cutlass and my 81 El Camino

BurnoutsAndRotorblades thanks alot fam .I'm be doing a 8.8 swap aswell soon shorten it the whole 9 yards

They are not.

@@BurnoutsAndRotorblades so are the ones you used from a 2wd blazer then?

It didn't come with a true proportioning valve. The combination valve is more of a safety measure to cut off fluid to an open circuit. It is fine to leave just as it was installed from the factory. I have years on this setup with zero issues and I drive the crap out of it.

When bleeding the brakes starting in the rear did you get the fluid to flow real good out the back .mines flow enough to put half in the to the fill up the tube halfway but it won't flow into the bottle like the front

@@Nutflame55 try cracking open a front and rear at the same time. that will reset the combo valve. Also, I went to school with a kid named Joshua Pridgen in New Braunfels Texas. You wouldn't happen to be from there would you?

I use the bleed tool. I just didn't get a lot of flow from the rear the brakes are working but the pedal is a little soft. And no I'm from Savannah Georgia

they were a few hundred bucks. I would say, after all the abuse thye have survived, it was well worth it.

I have used 2wd and 4wd backing plates. The 4wd backing plates change the position of the caliper so they do not contact the frame when the suspension compresses.

@@BurnoutsAndRotorblades are you talking about moving the calipers from the front to the rear? Because I've heard you can take the two-wheel drive flanges and just switch sides and it'll do the same thing.

If I remember correctly, that is an SN95 axle which is different than the Foxbody version I used. So, I don't have any measurements to give you. I would start off by measuring the mustang axle shaft for a baseline. Maybe knock all the studs off the stock axle, install the brakes and see how everything lines up. Then you'll know if you need to go in or out with the length. Take all that information and give it to Moser. Make sure you tell them that s10 blazer discs will be going on the end so they can make the lug pattern and axle end match the blazer disc dimensions if that's what you're going for. For that, when I called they told me the best thing is to measure the blazer axle hub you get the discs from so you can just give Moser those numbers.

The SN95 rearend is much wider than the foxbody. the foxbody is .75" wider than stock. I didn't want to buy new wheels and I didn't want different backspacing front and rear.

Check out the other video on my channel for all the info about the 8.8 swap. As for what else you can use this on, it depends. as long as the backing plate is centered on the axle tube and the offeset allows the caliper to have a full range of motion, I don't see why not. Just measure and shim if needed.

I have no idea about interchangeability like that. I'm sure there are mustang Guru's on the mustang forums that could help you out.

I put stock wheels on the back and they worked. I never tried on the front though.

Can you run a 15 inch wheel with this set up?

Gbody rear end needs to trimmed an then drilled too match the holes on the brake brackets

I don't know but. . . The Grand national is a Gbody so I don't see why not. However, if I'm not mistaken the Gnat came with a good rearend. not the 7.5 that plagues other G Bodies. Double check that on GBodyforum.com. There are a lot of knowledgeable folks and a wealth of resources over there.

I had a machinist friend custom make some after failing to order the right size off of that jungle website.

I did not add a proportioning valve. Everything I did is in the video. I guess because I did all the Blazer brakes it was still pretty balanced. It still works more than a year and hundreds of burnouts later. Usually if I had to do something different I put it as a note in the comments.

Not sure to be completely honest. . .

There is a thread on Gbodyforum ( gbodyforum.com/threads/another-blazer-brake-question.70882/page-3 )but here is the cliff notes. The 4wd disc "hats" are deeper putting the disc further inboard on the axle and making the stock backing plate/caliper bracket unusable. The reason this works on the 4wd blazer is because the 4wd axle is longer than the 2wd pushing the disc out and making the disc line up with the caliper at the axle flange. The only way you could use 4wd brakes would be to discard the stock mounting bracket and make one that moves the caliper inboard. If you use the 2wd discs, everything else from the 4wd will work.

No, but it's narrower. So, the width and mounting positions are closer to the stock GBody reared. You can use other rear ends but they may need to have the length changed or weld on different mounting brackets. The fox body rear end is a bolt on affair in both respects.

I used 2000 2WD S10 Blazer brakes. I know there is a big range of years for the same parts but that’s what year I used.

@@BurnoutsAndRotorblades Thanks for the quick reply. I figure worst case, I just try and mount them and see what happens. I can also take the camaro calipers to the store and compare them against the s10s.

I believe most guys call those "LS1 brakes." While I dont have any specific knowledge of whether or not those work, there is a ton of support on GbodyForum.com. Also, They look about the same as S10 Blazer rears.

@@mathewshackelford8037 did Camaro brakes work ?

They did fit but I’m also running a Ford 8.8 with Ford 9” housing ends from Moser that are designed for the small GM brakes. I’m fairly confident they would have fit just fine on the factory 7.5.

@@mathewshackelford8037 yea I have a 8.8 from a fox body, can I buy housing ends? And adapt them or they need to be welded on ?
