[Blacklespaul]

Trying to change rear pads, For some reason the freakin rear brake caliper won't compress, its the parking brake side but I disconected the cable,still won't budge with my chanel locks, had no problem with the front pads...wtf??!
Any help would be sooooo appreciated.

Frustrated in jersey...

I haven't changed the brakes on my Civic (its new!) but on my Eclipse I would open the brake fluid reservoir a little bit, and that would relieve some of the pressure. Just be careful not to spill any out.

i work at ford and on the small cars with rear disc i have to use a special tool to push them in.. the piston inside the caliper has to turn while applying pressure to turn in clockwise or counter clockwise deppending witch side... don't know if honda's the same.. whatever you do don't open and brake lines.. could cause air to get into the brake system then it will be a major pain in the ass to bleed everything out... don't know if i helped any..

Here's a DIY that might help!

there is an attactment that fits in between the lines. as you can see there is like a cross:


to compress this you need


the one with the two indents as shown in the picture are the ones you need to fit in the cross to then compress,
and instead of going straight back like the front wheel, the rear caliper twists like a screw and then compresses.
hope this helps
if you do not have one of these what you do is stick a screwdriver that will fit in the indent and twist it clockwise.

Thanks so much for the awesome help guys!
That explains everything! Thought I was going nuts...
Might as well pick up a caliper compressor, right tool for the jo8.
Thanks again!

Just wanted to add one thought. The kit pictured above is probably excessive.

Working on Hondas, the only two brake tools I've ever used can be purchased from O'Reilly Auto Parts.

For screw-type rear caliper pistons:
Lisle 28600

For press-in type front and rear caliper pistons:
Lisle 24300 (mine is actually a little different from that one; it doesn't have a hook on the end, but it works the same)

To facilitate pressing or screwing any piston inside the caliper, I recommend cleaning the boot first so that no debris gets trapped inside the boot when it collapses. If you have the time, there's no reason not to do it. Also, once you clean it, spray silicon spray on it. It will go back in a lot easier than trying to compress it dry.

So Blacklespaul did you get your caliper straightened out?

NO!!!!! Not on the rear disc!!

You are going to need a special tool which will attach to the piston and turn it while compressing it at the same time. You should be able to go to any auto parts store and rent one.
