I'm thinking about converting the rear brakes to discs... been seeing these rear disc kits for 67-69 Camaros and Firebirds that use the caliper for the emergency brake.



Wondered how many people have used similar kits or put together their own setup using Trans Am parts and Cadillac parts plus some brackets.

I remember when that style first came out in the 80's. I worked on lots of Rivieras at the Buick dealership with those rear disc brakes. Worked on even more, both Buick and Cadillac, at my shop later on. Perhaps they have since been improved since that early design. I have no experience with any of the kits, or with any of this type after about 87.

They worked fine for folks who set the park brake every time they parked. For those who never used the park brake (i.e. 95% of the folks driving automatic trans cars) there were chronic low pedal issues. We tried repairing several of the rear calipers, but with limited success. Most of them required new calipers to fix the issue.

Very poor option imho. Check out LS1 rear brakes from fourth gen F bodies. Easy to adapt and much better operation and parking brake. Spacer plates are around $40. Used brakes are easy to find.

Mine worked for a few years; manual trans and always set the E-brake. Then trouble and couldn't get replacement calipers to work after a lot of labor hours. Finally bailed and went Wilwood. I wouldn't do it.

Thanks for the advice Don. This is pretty much a DIY deal with minimal expense. I'm seeing bundles like the one pictured below on eBay for just under $200 shipped. Its listed as:

93-97 Camaro SS Z28 Firebird Trans Am WS6 LT1 11" Rear Brake Kit 1107-12

Since I've got staggered shocks, do those $40 brackets you mentioned resolve the problem of mounting? I'm running 17" wheels now... probably will not go back to the 15" X 8" rally wheels. Has anyone done a pictorial on here showing the installation and parts that are needed? The 2nd picture shows a bundle thats supposedly a Saturn setup... no rotors. Don't know if thats the same or just a lower end model brake.

Pretty sure you want 98-02 brakes.

There are some good threads on this forum on how to do the swap and account for staggered shocks.

If you don’t want to do all the DIY then Tobin at Kore3 can set you up with a similar Corvette based set up:

So there is no "DIY" disc brake alternative to the ls1 98-02 brakes that will allow you to use 15" wheels? My car is not an automatic, is always parked in a garage, and in addition to using my emergency brake, I almost always park my car in gear when out at a car show or cruise night... or just even going to the ice cream store with the grandkids.

Tobin is the man when it comes to brakes 👍

I’ve work with him on several builds.

S-10 rear discs will fit under 15" wheels and are very similar to the 98-02 Camaro brakes. Drum in hat park brake, similar calipers etc. It's been over 10 years since I messed with this stuff and I forget the details, but there is a difference between 2WD and 4WD stuff and I forget which will work or if it's a mix of the two. Dig around - the info is out there, or used to be!

I think the rear kit Right Stuff sells are based off of those Caddy parts. I helped a friend install them on a 65 Chevelle. They pretty much suck.

Of the 2 photos you posted the set on the right looks like what's called the "LS1" - 90-02. The other set is early 4th gen f-body and the park brake isn't very good.

Thanks... I'll look into the S10 brake option and see what I come up with. And yeah... I looked at the Right Stuff basic rear discs and they all have that side mounted parking deal. If money was no object, I'm sure there are plenty of options... I just want basic rear discs and a parking brake that works like it should.

Just baffled that if that side-mounted parking brake was so bad... how did GM ever approve its use for so long? No lawsuits, no cars rolling away and crashing?

I've done a couple of Right Stuff rear disc conversions with no issues. you need to adjust the parking brake before you bleed the calipers.

I have that type,with the caliper E-brake. They came with my 9" rear so price was right,otherwise I would have matched my Wilwood fronts. They do work...
But since it was my first experience with them they were a PITA to set up, it took me a couple of days fiddling with them and figuring out the ratcheting e-brake set up procedure.

Next time I have to touch them for any maintenance,they will be going in the trash.

I would not waste my time on them again. But like I said, price was right and they work...

I might have been a bit harsh - I remember thinking the park brake/caliper deal was kinda hokey. Also remember that you have to remove a caliper bolt and level the caliper in order to bleed.

Here's the info I remember about the S-10 swap. It's on a 2nd gen. S10-Blazer rear disc conversion | NastyZ28.com

Thanks for the link Al. I read through the entire thread, and this morning I sent an email off to Woddy (Eric) for some advice and long-term opinion. The S10 mechanics kind of appeal to me more than the RightStuff setup, but I've heard a lot of people do run the RS setups with no big issues once they figure everything out.

I wouldn’t be surprised if the braking force of those metric calipers was less than the factory drums. There is probably an analysis out there somewhere on the web....

I'm using 2000 Blazer 2 wheel drive on my '87 El Camino because of shock location. You can't use 4 WD rotors they are too deep. 4WD have one caliper facing to the front and one to the rear, this may work for staggered shock mounts. The Monte Carlo SS and El Caminos and etc. have both shocks on the rear.
