I am trying to replace the pads on my rear disk brakes on my 1991 CRX.

For some reason, the brake piston will not retract. I dont have enough room to put in the fresh pads, as well as get them around the brake rotor. What is going on?

I need help fast, as I am trying to get this done tonight.

EDIT: I have tried to push in the piston with a clamp, and pry it in with a screwdriver...it wont budge.
Thanks

Common guys, I am desperate!

 

I have no idea about a '91 crx, but on many modern hondas, the rear piston is slotted so you screw it back into the caliper. Is your piston slotted at all, or is it like the fronts?

 

The piston must be turned into the caliper. Screw it in and be sure to align the groove in the piston so the nub on the pad will slide through when installing the caliper.

 

i responded in your other post

 

there is a tool for that as well if a pair of needle nose pliers wont work. turn it in clockwise till the piston bottoms out, then line the slots up at 12-3-6-9 o'clock.

 

Well, it took me 14 hours to do the rear brakes, and replace the rear struts. What a pain in the ***. All the bolts were seized....one bolt broke of...I had to drive back to the city to buy parts, come back. I am just exhausted.

I just ended up taking the caliper off, and using a hammer to knock the piston back into the caliper.

Problem is now, that my breaks a bit squishy. I don't think I bled the brakes properly. Its drivable, but it seems much softer then before.

Any tips there?

 

LOL. If all else fails, hit it with a BFH. I hope you didn't **** them up too bad. The pistons should be turned in as was allready stated.

 

I think the pistones were simply "stuck" in an outward position. I mean, the old brake pads were worn down to almost nothing, and that meant that the piston was sitting out a bit more than ussual. When I put the new pads in, I had to back everyting off on the caliper with a hammer and a vice so I can get the calipar spread enough to slip it over the rotar.

And yes, it was a BFH!! Little sledge hammer type thing. I just tapped the piston untill it went back in.

I am scared to attempt the front struts today. I dont want to break another seized bolt. Part stores are not open sunday.

EDIT: Whem I tool the calipar off, the piston was NOT turned in on its own. It was out and it made it impossible for me to get the new fresh pads on, as well as get the pads over the rotar.
