Quick rear brake question

[trinistylez]

My cb has 4 wheel disc brakes. Lately the rear seems to be squeeking while coasting, did some research online, seems as though it may be time to change the pads. I have pads for it already, I was looking at a diy online how to replace the rear pads. The video I saw said you have to rotate the piston as you compress it in. I do know pushing the piston in isnt all that easy, i have the tool to do it which makes it easy, but it doesnt rotate the piston.

Would I do any damage to the caliper if I were to just press the piston back in not rotating it?

It won't do a single thing. It won't damage them, put you won't get them to compress.
Use a large screwdriver, turn it in with that.

Go to Harbor Freight. In the automotive section they sell a hollow cube like tool that has multiple pins cast into it that allows for a universal fit on pretty much any rear caliper that requires a twisting motion to retract the piston.

a standard 3/8th's socket wrench fits into it, I just use a 3/8th's extension with mine to make it a little easier so i can push in at the same time. You can find it for about 4-6 bucks depending if they have it on sale.

Thanks guys. Ill probably try the socket idea... Seeing as how thats what i have on hand at the moment. The noise is rlly starting to piss me off

i agree with the previous post and i will add it helps to spray a little lube between the caliper piston and the ruber dust boot.
that will keep the rubber from sticking and twisting.

if you see that the rubber dust boot is ripped it would be a good idea to replace the caliper with a remain unit.

if it is too difficult to turn the piston you can open the bleeder with an 8mm that will make it easier.
the fluid will come out the bleeder rather than forcing the fluid all the way back to the master.

Would i not have to rebleed the brakes then? I have no clue what to do when it comes to that. I always usually had a mechanic service my brakes because it is something i do not like to take chance with.

I got one side done today and took me about two hours and ton of cursing!

no you dont need to bleed them from just opening the bleeder, as long as the master resevoir doesnt go empty.

[trinistylez]

So just crack the bleeder loose, rotate piston in... Close bleeder and done? I really do not want to take a chance on air getting into the brake lines.

[budget street]

dont worry air isnt going in the bleeder.
it doesnt work like that.
understand the bleeder is lower than the master resevoir so the fluid is heavier than air and will not allow the air to go in the bleeder.
gravity is working for you.

if you have any problems post back
