Rear Caliper Piston Popped out..too far!

[93240sx]

Hi,

While inspecting the left rear brake (noise) I removed pads and screwed in the piston (caliper). When I put hte pads and capliper back and pressed on the brake pedal the piston did not go back. Took it apart and then pressed on the piston and it then came out. Unfortunately too far! It does not seem to want to move back in. I have tried screwing it but I believe it is too far. Any ideas would be greatly appreciated!

Thanks,

Used "C" Clamp (5").

Dont use a C clamp , you risk breaking the caliper , AutoZone sells a small tool to help turn the piston back in , since its kind-of hard to turn.

I had the same thing happen on the rear in my gf's 240. She ran the pads down to nothing and it allowed the piston to come out to far. I screwed it in for 20 minutes to no avail. I disassembled the caliper and all seemed ok, but the first thread in the piston looked a little odd. But, when I tried screwing it in it wouldnt go.

I had to take my ratchet and put it between the piston and caliper and pull the e-brake lever (on the caliper) and force the piston into the ratchet and turn it with needle nose while it had some pressure on it. It fianlly started threading again.

Dont know why this happened, but I guess it was from running it without any pad material. Hardest longest brake job ever, as mine take no effort and little time to do.

Well thats not true the time I threw out my neck doing her fronts was the worst, as I was in extreame pain and put everything back together as fast as possible before I became immobilzed. Do not try to brake caliper bolts loose that you do not know how tight they where put on with out some sort of leverage I was pulling up on the 3/8" ratchet and heard the nastiest ripping type noise comming from my neck Good times

Ouch , that sucks... Your gf has a 240 as well thats cool. Like i posted before you cant c-clamp them there is a strong posibility that you will F**K up the caliper. I just learned this lesson last week , a 70 dollar mistake.

I didnt c clamp this one it just never went in while tunring and applying had pressure, and required a lil pressure while turning to get it back in.

Yeah she has a 240 though because I told her to get one hehe. She had an 84 accord and a 89 probe before that and I *****ed and moaned everytime I had to work on em. Now its not a problem

Well this "tool" makes it a hell of alot easier to turn them in. Its like a dollar...sheesh.

i bought the tool, it cost like 5 dollars, and is universal and you put it on a 3/8a" drive and can easily turn it. And it is easier to turn with it. Also You can break the rears if you use a c-clamp. THey need to be turned clockwise (needle nose will work too). THe front uses a c-clamp. Well hope that helps.

I applied small pressure (on the rear caliper)using the c-clamp since it has too screw in. But if the piston has popped out to far the piston will NOT screw back in.You have to use a c-clamp or some special tool. Anyone know what the name of that tool is?

Also replaced pads in the front. Cleaned and inspected and then bled the brakes (ABS). I have noticed that the brake pedal has not come up any higher with the new front pads. In fact the brake pedal seems low to me. I thought that once the new pads were in the front the pedal would rise.

Also, I noticed that I did not do the bleed in the sequence that is in the Nissan Shop Manual. I did RF, RR, LR, LF. Never bled the actuator. S/B bleed RR, LR, LF, RF..Actuator R, F.

Although the pedal action is the same as before (I did the brake service) the bleed seems fine. Anybody have problems with the Brake BOOSTER in this model.

Thanks for all of the feed back.
