The piston will be in the center of the rear caliper, the one the hose attaches to. See the page. It's just held by hydraulic fluid so you can push it back into the caliper with a C clamp. Caliper must be removed and the inner brake pad pulled out.

OK, the thingee just above the hydraulic hose connection is the only thing on the inner side that even remotely looks like it could be pushed in...is it the piston? And if it is, and I get a large enough C-clamp, do I have to remove the inside pad? How would I do that without taking everything apart again? Thanks!

On edit - it seems that things is the bleeder screw and not the piston? I sure an not seeing anything that looks like this picture, but maybe when I pull the caliper it will jump up and smack me in the face!

you are correct. That "thingy" is the bleeder nipple. Rubber cap protects it and keeps junk out. To bleed the system you'd put a hose on it and loosen it as a helper pushed fluid thru from the front OR attaché a suction unit to it, loosen it and pull fluid thru. Since you did not break the seal and allow air into the system, you don't have to worry about bleeding.

Pad is usually just held in by either springs or tabs; it just sort of 'snaps' into the caliper. Pad rear will ride on the piston and the piston will be a circular steel "thingy" about 2"-3" across, in the center. Sometimes not easy to push back in, but the C clamp will do it. Center the clamp and use a socket to make a spacer if need be.

Usually, they will push in until flush with the caliper body. Then re-install pad and it should give you enough clearance that the rotor will now spin pretty freely. You may still hear some minor metal/metal rubbing but that is normal. NOT binding up, however.

This is NOT going well! I pulled the whole caliper off, then popped the pad out of where it was seated, but there are three springy thingees on the rear of the pad, and there is simply no clearance between the part with the piston and the front pad to pull the pad out. I possibly could bend the springy thingees but I don't think I should do that as it would probably destroy their functionality. It looks to me as though I have to split the caliper again to remove that pad. I will see if I can get a decent picture, but color me frustrated to the max right now, and I am just running out of steam...and confidence!

On edit - couldn't get a good picture, and it is time for me to call it a wrap for today. At it again tomorrow.

Just think how easier the other side will seem! Wink

In all seriousness, post a pic. It's probably springs that hold the pads that are in the way...probably. They are designed to flex and keep everything in place. Don't bend them. Just unscrew to two bolts and take the caliper apart. Once you get the piston pushed in and the pad re-installed, it will all go together. You've already done the other part of installing the rotor etc.

Good call. When my cars really piss me off...I walk away, close the garage door and turn the light off...

Pat there are a lot of videos up on YouTube that you can watch to get an idea. Etrailer.com has a lot also. Looks like your having fun anyway.

Pat

Here is Timken pdf showing various bearings issues

Good Luck

OK good luck

How do are the calipers?

Sometimes the brake calipers need replacement.

This picture clearly illustrates the current predicament I think. The inner pad is popped out of where it was seated. You can see the clips or springs under fixed part of the caliper. The inner pad cannot be removed because the clips or springs do not clear the fixed part above them and the outer pad blocks tilting or otherwise moving the inner pad to remove it.
