Thread: Front brakes locking.

Tweet

The caliper does slide on those pins! They need to be clean and free of rust or dirt , debris! As the piston extends out , pushing the inner pad against the rotor, it simultaneously provides the clamping force drawing the outer pad against the rotor!

OK as you apply the brakes the piston moves out. pushing the inside pad into the rotor AT THE SAME TIME the piston is pushing the back of the caliper assembly towards the frame of the car. Thus clamping on the rotor. The outside shoe(PAD) is stationary with the caliper... As the pads wear the cylinder stays out that much along with the inside pad. The caliper moves toward the frame of the car as the pads wear The inside of the pins is attached to the caliper with threads. I realy hope thios helps

Yep the bleaders belong on top. I just put that one on to show how they work.. When it goes together the right one will be on the right side and so on.

your setup is correct. I realy don't know how to explain it any different

Got to look outside the box.

I guess I am going to have to look at that a little closer because if that is the case I have it backwards.

I guess I am not making myself clear I know how they are suppose to work. The problem is that my calipers do not have threads for the bolts to screw into. The threads are in the mounting brackets and so when I tighten down my bolts it secures the calipers to the brackets so they can't slide on the bolts and activate the outer pad. I don't know if you will be able to tell from my pics or not.

Well don't I feel a little stupid right now. I just came in from figuring this out and here you have it all spelled out for me. Again.lol I had a little tunnel vision going on and thought the sleeves in the calipers didn't move. I tightened up the outside pad and cleaned a little paint off the sleeve in the calipers and greased the bolts/pins but it still binds up for some reason. It actually bound up as soon as I tightened it down.The mounting bracket must be a little off square. I will look into it a little more tomorrow. Thank you all for your patience!
