Adjusting brake tension.

[Guest]

Hey all,

I just want to know how to adjust the brake tension on my front disc brake. It seems to be scraping a little, and making some noise. Any help at all for diagnosis, or with this problem is useful.

Thanks

There is no way to adjust "tension", but the seals in the calipers are supposed to pull the pistons back just enough so you don't hear them rubbing on the disk. If you have not had the calipers apart recently to know just how clean the pistons are, I would suggest that you take them apart, pop the pistons out, make sure they are squeaky clean. Pull the seals out the caliper, clean the groove in the caliper that the seal sits in, put it all back together, lubricating liberally with fresh brake fluid. As you reassemble the caliper, make sure the pins are clean and lubed with hi-temp silicone brake grease.

Steve it could also be an out-of-true rotor.

You sure the spacers are in the right way?Make a real mess of things if they are in the wrong way.Found this out the hard way

True, depends on how regular the sound is. An out-of-true rotor will likely pulse with each rotation.

SVSooke's suggestion of checking spacers is good, too. Just eyeball the caliper from the front or rear to see if the disk is centered in the caliper.

Very true on the last part. My dragging I had a long time ago on the brakes was more of an issue of the wheel and/or calipers not being tightened correctly.

Also make sure the caliper is square with the rotor and not cocked to one side.
