bleeding the brakes...

[crypt2k]

so my rear brake pads need replacing... I tried to do it yesterday. Changed the pads and everything but that big *** piston wont go back far enough... so i heard that i have to bleed the brakes.

How would I go about doing this... I just want to get the rear pads in... nothing more.

Thanks before hand.

IIRC in the rears you have to stick pliers in there (or a special tool made for this) and turn the piston itself clockwise. It should screw back in and give you enough roon to do whatever.

Are you doing this? Bleeding shouldn't have much to do with this, although you may want to try taking the cap off of the brake fluid reservoir while you are doing this if it is still not working.

I replaced my brakes not too long ago, just make sure to have the piston screwed back and I believe the front of the caliper also pulls forward to give more room. I did all my brakes simultaneously so I don't recall which you screw in and which you have to just push in...sorry.

well... the rear brakes are the ones with the screw in piston.

I will try your open reservoir technique and report back... thanks.

[crypt2k]

thanks man... i worked!

hey, cryptk just wondering, I tried to do my rear brakes and got the tooleven w/ the tool the piston was extremely hard to turn, and I remember spending like an hour turning it, but it gets to a point it won't go in anymore so it won't clear the new pads, but it STILL turns...

so I tried bleeding it and it still didnt work

so then I just took it to a shop lol, but yea tell me did you have the same problem? how far did you have to turn the piston in?

next time I will try the open reservoir thing

The very first week I had my 240, I had never seen calipers that you had to twist the piston to get it in. We tried compressing the pass. side with a c-clamp, my arms hurt after it, but I got it to go. I then found out before we started on the drivers side was that you had to twist them in order to go in. The drivers side was much easier, by twisting.

lol

Yeah the first time I has seen the twist on was on my 240. I like it 100x better than the type you have to clamp, sooo much easier.

I wonder why only the rear brakes are like that?

[ricebike]

that's for the parking brake/e-brake function...

when the pads wear out, the pistons rotate slightly counter clockwise to keep them in constant contact w/ the rotors when u yank that handle.

liu...yeah dude... it worked... i opened the reservoir and I was able to crew the piston back in all the way... or at least enuff to give me clearance.

bringing back a very old thread from the dead to say THANK YOU!!!

God I love the search function!

I would have stared at those calipers for hours trying to figure out that they twisted back in.

Thanks
