Rear Caliper Piston Retraction ('87/8 Calipers)

I'm having a problem getting the piston retracted back down into the bore. It extended easily enough by turning it counter-clockwise with a pair of needle nose pliers, but turning it clockwise does not seem to be running it back down the hole. Using a brake pad seperater was a futile effort - the plate on the tool started to bend.

Suggestions?

Thanks,

Brad

If I remember correctly, I had to open the bleed screw. I, guess, the piston builds up pressure when you try to turn it back in. I hope this helps.

I JUST did this last nite. <G> Open the bleed screw...

You wil have to bleed the system if you do this, so have some brake fluid on hand but other than that, it is THE way to do it.
Also, best way I saw to screw them in was, pull the rotor off the axle. Then bolt the
support bracket and caliper to the axle like
it normally goes. (No pads)

Bolts only have to be finger tight.
This holds everything so you can use two hands and apply some pressure to the caliper
and needle nose pliers. We had two of us working on it so I held the caliper from sliding too far on the slider pins, while my partner ran the needle nose pliers. He put the pliers in the slots, then put a small breaker bar between the handles on the pliers to get leverage. It still took some work.

Great, now I feel better that two of you have said the same thing - thanks for the details...

I picked up an attachment tool that fits into the slots on the piston from one of the auto parts stores .... I don't remember which one or the cost. It makes it a lot easier than using pliers and you might save a knuckle or two!!!!

I know at Advance where I work we have it for $3.00 or $4.00 . Worth it at twice the price to avoid the frustration!

Thanks guys, this worked out perfectly by putting a hose on the bleeder and cracking it open a bit. The piston easily screwed in at that point, just using a pair of needle nose pliers. But certainly, the proper tool would have made the job even easier.

Thanks again,

Brad
