Squeak from rear brakes after Right Stuff conversion....

I've tried tightening up the e-brake. I have also put anti-squeak on the pad surfaces. And I have put anti-squeak grease/lube between and pads and the pistons

We have had good results at work with the anti-squeak stuff I used. It is a product from MOC We use it on all our brake work (Mercedes Benz dealership)

I still have squeaks at low speed with my foot NOT on the brake.

Ideas?

I didn't have this squeak with the other rear disc setup I took off.

Re: Squeak from rear brakes after Right Stuff conversion....

It might be possible to have a caliper sticking, did you replace your brake fluid when you put disc brakes on the rear? I have seen some pads just make noise when they are new and i think it just the pad itself but for it to be doing it with no pedal applied it has to have something keeping pressure on it i would think.

I personally dont see the point in using the stop squeak stuff, sometimes brakes just make noise and greasing them wont do anything... if that stuff is grease. idk

Maybe try taking it out and braking hard several times without stopping to see if it was a bad stop in the pads. Sometimes that helps.

Hope i helped some, TJ

Have you called Right-Stuff? They have a great customer service.

Re: Squeak from rear brakes after Right Stuff conversion....

It could also be the pad material squealing. On my M3, metallic pads are used and they squeal like a pebble is between the pad and rotor until faster speed and heated up.

You might try a "beer can" shim behind each pad, empty the can first.

Thanks for the replies. I will be talking to Right Stuff in the morning about another issue, so I will mention the squeaking.

Re: Squeak from rear brakes after Right Stuff conversion....

I am using the pads that came with the RightStuff kit. Did you get the splash shields?
If so, its possible the caliper and shield are rubbing, its a close fit there. Did you get the caliper shimming right?

Also on E brake adjustment, you need to find a medium in adjusting with the equalizer rod. If you go too far, you will notice it.
I presume you are using their rotors also.

Re: Squeak from rear brakes after Right Stuff conversion....

I used this stuff and no squeaks. It dries in a couple of minutes like rubber.

I adjusted the rears by putting a 0.030" feeler gauge between the rotor and outside pad, then activated the lever by hand until it clamped hard, then bled the rears.

Re: Squeak from rear brakes after Right Stuff conversion....

I could never get the e-brake to adjust by pumping the lever. I ended up taking the lever off and turning the hex to move the piston out to the caliper. Then reinstalled the lever and cable. Right now the lever is about 1/4 inch off the stop when disengaged. I get e-brake with the foot pedal down about 3/4 of the way down.

I don't know if you took the spring out, but it's easy to adjust using the lever with the spring removed.

No brake pressure pads dont squeek...if they do u will feel the pads holding if u jack the wheel up and feel the drag...or the hub will be warmer than normal
At the same time check your wheel bearings, thu they normally rumble when need replacing.
If the pads are free its not the brakes.

My Spelling is not incorrect...it is creative

Re: Squeak from rear brakes after Right Stuff conversion....

I put more anti-squeak stuff on this weekend. I had no squeal for about 2 miles. Now the rear brakes have a constant squeal that gradually turns into an occillating squeal when I pull away from a stop ,turning right or left. The noise goes away once I'm up to about 25 mph.

I've thought that it might be the rear u-joint, but I doubt it.

I can't find anything rubbing. Everything I've checked has had plenty of clearance.

I'm stumped:

Rotor has excessive runout. Check with dial indicator, anything more than 2-3 thou is unacceptable.

Re: Squeak from rear brakes after Right Stuff conversion....

Which MC are you using? If it's a disc/drum type, there's likely a Residual Pressure Valve in the rear portion which could be holding a pad against the rotor. Just a thought.

Change pads of a different material.
