I was noticing a notice coming from the back when braking, pulled the drums last night, was leaky brake cylinders. No a big concern, replaced with new ones, cleaned and adjusted the rear shoes, turned the drums. But I was wondering and have checked on search with no good result, Anyone done a rear disc conversion..? I am wanting to research some and you never know....?

Maybe wrong section???

Might have better luck in performance and brainstorming.

I've read some threads about it and the general consensus is that it would be very difficult to do and not worth the cost/effort. I have not read that anyone on this forum had done it. It was a disappointment to me that Bonnevilles did not have discs on the back even as an option. I know someone is going to chime in and say they are not needed, the front does most of the braking...yada, yada, yada. Fact remains, discs are a far better set up, and I can't believe they would have cost that much more to put on the car.

GM did put rear disc brakes in the 2000 models and up.
