How do you replace brake booster on a 04 buick rendezvous?

Answer 1

I just gave it a shot on an '02 (2002-07 use same repair manual from what I've read) and ended up putting it back on and now I'm taking it to a mechanic. To start you need to remove the master cylinder and disconnect the hose from the booster. You also need to open the lower dash under the steering wheel and disconnect the brake pedal and remove 4 nuts from the brake booster...one of which is behind the steering column and not exactly easy. The tricky part is actually getting the brake booster out which appears to require taking out a fair amount of the upper motor. I tried disconnecting the brake lines from the distribution box and pulling it out to open up some space but it wasn't sufficient.

If you don't have a good deal of experience I suggest taking it to a mechanic. It's probably going to be a 5-6hr job so $400-$480 in labor depending on the mechanic. I bought the part for $140 so if they try charging you $392 like one shop tried charging me, you might want to go elsewhere. Sorry I can't give you anymore specific instruction, but I hope this helps.
