Hey everyone, I have a 96 Cutlass Supreme that needs new rear brakes. I understand how to install them, and which parts I need.
I have never done a brake replacement myself, so the real question is:
If I put on new rotors and brake pads on my two rear wheels, will I have to bleed the brakes??

WooHooo...I know what I am doing after work tonight then...thanks Aaron.

as long as you don't open up the bleeder or take the break line off then no air will get in the system and you wont have to

Ok that's what I thought...I just need to get some pads, rotors, and a c-clamp to push the piston down...not going to keep the car much longer, but brakes are kinda important.

More or less yes, might want to look up a how to online...

I did my brakes just a few days ago, replaced them with semi-metallic that came with my R1Concepts. Even tho my OEM brakes where only worn by maybe 30% they feel so much better. If you get brake fade in a 1 pass 120 to 0 moderate braking you need to change your fluid. It should be changed every year or 2 to keep its boiling point high.

does it have abs? If it has abs you dont want compress the caliper without opening the bleeder. It may be a screw in type caliper on there also. If it is you will need a special tool or a big pair of channel locks.

I can almost guarantee those rear brakes need the special little box tool to screw the caliper back in.

Yes the tool would be needed, however I am not doing it anymore. Took me over an hour to get the wheel off...everything is very rusted...the parts would be just over 100 bucks, my local brake place with do new rotors and pads for 150.
So I gave up...the caliper was never coming off without an air gun.
Thanks anyways guys....

Yeah even though you had the brakes changed, I highly recommend purging your fluid, especially on a 12 year old car - that fluid would be nasty.
It's cheap, and like Sint3k said, will restore pedal feel.

I power flush my brake system completely every 20000kms or 2 years. This is important esp on abs systems due to the high movement of fluid in the system, a contaminant is quickly moved in the system and affects the whole system. On another note here: Never collapse a caliper without the bleeder for that caliper being in the open position. By it being open while collapsing the piston any contaminant or burnt fluid will be expelled and not forced backwards into your system. Then close the bleeder and top off the master.
