Brakes Making A scrubbing Sound when applied?
My brakes have just started making a scrubbing sound when I apply them pretty stern. It only seems to be coming from one, and it will stop if I apply them stern, and then let up and reapply them.
I just had the brakes replaced on Truck and Trailer 3 months ago, and have not had any problems or noise until now. Any suggestions on what to check for this? |
could be a simple thing like sand or gravel in your drum.
Only way to find out is take off your wheel |

jack it up and check wheel bearing endplay. check for dust shield to drum contact. but, you likely will pull the drum, dump out debris, scuff the lining and drum surfaces, then re-assemble to make it go away... maybe even re-line. |
Thanks, found the sand and got rid of it. smooth sailing now, or should I say braking now.

Sure a lot easier than pulling the hub/drum, replacing the seal etc., just to get the crap out of the brake shoe - drum interface area. Note: when using compressed air around brakes, always use respiratory protection, as brake dust is hazardous to your health. After blowing out the dirt, be sure to properly readjust the brakes and re install the dust shields. |

most outboard drums can be removed as quickly as a dust shield anyhow. ... most any service manual will specifically tell you DO NOT use compressed air to remove brake dust, they will usually recommend a damp cloth or brake clean. |

in today's world, unless specified otherwise, i assume outboard... we all know about asbestos, and the fact that when the fibers become airborne, they do not settle to the ground for a long time..., that creates a hazard for other techs in the shop, or your buddy that's helping you, or you (after you've removed the respirator).
