The right front wheel cover recently has been accumulating what I assume is brake dust grunge about twice as much as the other three wheels. I’ve run the car through a good wash several times so know that this is a repeated ongoing situation the past few weeks. That wheel is NOT hotter to the touc…

UPDATE: Brakes are all good! Nothing sticking. Both front brakes are at 7/32". Both rear brakes are at 6/32". Original brakes, 54,000 miles, 8 years. BTW, brake lines were flushed and new brake fluid last oil change 5,000 miles ago. Woohoo! So, just need to scrub that one wheel cover better …

Have someone check if the brake hose to that caliper is acting like a check valve. When this happens, the brake hose prevents the caliper from releasing the brake pads from the rotor immediately when the brake pedal is released, and creates more brake dust than the other wheels. Tester

@Tester Thank you. Will do. I hadn’t thought about the brake hose being the issue, although as often as that is mentioned in discussions here I should have. At eight years old, I probably need to have all degradable hoses and belts looked at. Again, thank you!

That corner is dragging more than the other side. Given the age, agree it could be a brake hose. Could be a sticky caliper or slides, too. I’d bet the brake pad on that side is a little thinner than the other by now.

Yeah, brake check, caliper check, brake fluid flush.

Will have the brakes and all compinents checked. Brake flush and all new brake fluid was done last year, less than 7,000 miles ago.

I spent some time thinking about it and I don’t have any new ideas but I thought about my last brake job. My front brake rotors looked like the rings of Saturn. Some parts of it were smooth and shiny and the other areas (rings) were rough. I can imagine that the rough spots were making extra dust. E…

Good idea about the brake cable above. Another idea, the wheel cover may be more sticky than the others b/c of something or other that’s sticky is coating the surface. Try cleaning it off with some sudsy warm water.

1 of my tires is worn much more then other 3. Evenly worn. No edge wear or feathering. Tech said it might be due to brake dragging? Well, the right front has more brake dust but this tire was on left side. I rotated it front/back and never switched sides. All tires are at 1/2 tread and this one is …

I think a brake hose acting as check valve is rare. More likely the caliper is not sliding on its pins to the place where the pads have equal contact and pressure against the disc. It’s not a hard squeeze that would result in a hot disc; more like a light dragging on one side of the disc that produc…

Excessive "brake dust" on one wheel cover

Backyard mechanic and I’ve seen it. A guide to hold the hose away from the shock rusted and was pinching the hose…acting like a one way valve.
