LS1 rear disc brakes and larger Brake Booster

[Chris McDade]

I wanted to give everyone a upgrade on some brake issues i've been fighting for a while now. I had stock rear drum with vacum brakes. Car would not hold boost or stop very well. Brake peddle would bottom out easy. I decided to upgrade to the rear LS1 disc. I bought the brakes from a board member that never installed them. I had to make some brackets for the ebrake but, other than that everything was there. Took about a month to install them taking my time. Drove the car and the stopped better but, not like a expected. I did some research on the larger brake booster and decided to give it a try. I ended up buying the one from a later 80's chevy caprice. I got it installed and went on a test drive. This thing made a big difference. I can lock up the rear brakes now, I have more brake peddle travel, and I can hold more boost on the line. If anyone has thought about making this change you should do it. I will try to post some picks of the brakes and booster later today or tomorrow.

Hope this information will help someone.

Thanks

Rear disc are from a 2000 Chevy Camaro. Brake booster is from a 89 Caprice. I reused the master cylinder I had. I gave the parts store my old booster for the core credit.

Hope this helps.
