Rear disk brake question


ZacksZ34

Recommended Posts

Ok im in nthe process of puttin new rotors and pads on my z34 but i have ran into a snag on the drivers side rear! I can seem to get the damn caliper cylinder to claps so i can get both my pads plus the rotor! The first time i took the wheels off i only had one brake pad the outside on wasn't even there! :confused?: How do i do I get the calipers cylinder to go in????

you need to rotate while pressing the piston in. You can get a small cube shaped item for like 10 bucks. Your rachet pops in there and you can then rotate the piston. On every set I've done except for one, it was a PITA and I really had to press hard on the piston (by hand) while turning to get it to collapse.

thats what i tough cause i bought that cube tool and we started to do it but we couldn't get to to go in far enough

 

 

Your caliper is bad, get new ones... Anyone who has experience with ratchet type rear calipers that have a decent amount of miles on them knows to buy new loaded calipers along with the rotors. Loaded calipers are really nice since not only are they new and will work correctly, but installing them since they already have pads clipped into them should only take 10th of the time it would to compress the old one, install pads, lube them up, and slap the shit back together..

yeah, before I swapped to the new style of brakes I put no less then 10 rear calipers on the back of it. just buy lifetime warranty calipers and bank on changing everything anytime you do rear brakes

You NEED to replace them in pairs if you ever want your rear brakes to work right..

I must be the luckiest guy on Earth. I have two W bodies; a '92 (120K miles) and a '93 (136K miles)...and I have ZERO problems with them. I did replace the rear calipers on one of the cars, but the new calipers didn't solve the problem--replacing the brake booster took care of the poor stopping power, though.

 

DON'T buy the stupid cube tool. Take off one nut, one washer, and one lever from the back of the caliper. Push the piston in with a c-clamp vice grip and a block of wood or the brake pad to prevent the vice-grip from damaging the piston. Why twist the piston to retract it when you can just let the threaded adjuster spin? Simple, easy, and no additional tool cost.

 

Seems to me that rear caliper problems on these cars are GREATLY exaggerated--but brake boosters do seem to be a genuine shortcoming and they don't get enough attention.

i'm amazed at how many threads there are on compressing those rear pistons. i've always done mine with channel locks or a screwdriver and has never given me any grief

I just replaced the rear calipers on my cutlass two months ago. Glad i work at a auto shop, since i got a huge discount on parts, and i was able to use a rack, plus all my tools are there.

 

But i have owned my cutlass for about 8 years now, and this is the first time i had any problems with the rear brakes.

I have to replace my z34 ones, the front mainly but also back. Fronts bang turns out the boots are fangled up and the same goes for the back.

 

As far as turning the calipers, I got that kit fron snap on with all the gm adapters in it. Mostly for myself, but you need it, specially on Z body malibu.
