I have a 2007 Honda Odyssey and recently had new tires put on and my front passengers rotor only has been scored (believe that’s the word) beyond belief. What could cause this to happen to only the one rotor?
There’s something wrong with the way the caliper applies the brake pad to the rotor, or there’s something wrong with the way the caliper is mounted.
Or, your brake pads are completely worned and scoring the rotors. Metal to metal contact is a better word for this. In any case,get them inspected ASAP.
Thank you I had new pads put on this past summer and the rotors we’re sanded even, it just happened in the last two weeks since I got the new tires and wasn’t sure if anything there could have caused it
Some markings on the rotors like that is to be expected, from grit from the road surface getting kicked up and lodging between the rotor and pad; but that seems excessive. I did some brake work on my Corolla last month and in the process inspected the front rotors. 200,000 miles on them, original to the car. I noticed a few grooves, markings, but nothing like that. Has this car sat for long periods of time? If so, maybe the rotor got rusted, and the resultant rust particles did that once it was placed back in service.
I don’t think the new tires per se has anything to do w/this but it is possible the installer banged or otherwise damaged the caliper while re-installing the wheels. It’s also possible the installer overly tightened the lug nuts or in the wrong sequence, but the symptom for that is usually that rotors got warped, not scored.
The advice above to have a shop look at this is spot on, both for your own safety, and other drivers. Do you hear any weird noises when braking? Do you feel the brake pedal pulsing? If so, make a mental note how it sounds/feels so you can tell the shop what you are experiencing.
Are you certain this happened only after the tire work? Is it possible it has been that way for some time, and you just happened to notice it while inspecting the tire work?
I’m a diy’er and if I had that problem I remove the wheel, the caliper, and a brake pads for a thorough look-see what’s going on.
Van has never sat for more than 2 days, it’s usually all over the place. I heard a grinding the day I had the tires done but it seem to come & go. I noticed the grinding noise bad yesterday and today when I finally got a chance to look at it that’s what I saw. Will have it looked at tomorrow. Thank you all for your help
A grinding noise can be due to the pads being worn out. Worn out pads will definitely cause that. Perhaps the tire thing is just a coincidence. The counterargument to that is that when you first hear the grinding/scraping sound the pads haven’t worn out yet, it is just the warning gadget installed on the pads that is making the sound. And that doesn’t damage the surface of the rotor. Another theory, it could be a caliper problem causing the pads to wear out really fast, just on that wheel. You might try feeling that wheel (be careful, could be really hot) after driving the vehicle a few miles to determine if it is hotter than the others. If so, that would be a major clue.
Some drivers aren’t as sensitive to grinding noises as others. On a radio show recently I heard about a driver who took their car to a shop b/c there was “something wrong w/the brakes”. It turned out the pads had worn clear to the metal, just the little ears holding it on, so thin that when the driver backed up with the brakes applied the pads were so loose they got thrown completely from where they should be inside the caliper, which jammed up the works and tore the caliper completely away from its mountings. Many thousands of dollars to repair.
This problem could be due to a seized brake caliper. Any unusual amount of heat coming out from that wheel?Hot metal smell? A lot of brake dust?
That is caused by your brake pad being worn out. The new tires have nothing to do with it. Most likely your caliper pins are stuck and the caliper is unable to float properly. Because it can’t float, it holds one pad against the rotor all the time causing it to wear out prematurely.
A good shop will replace the pads and rotors and lubricate the caliper pins. A lesser shop that may offer a better deal on pad replacement will want to replace the complete caliper for a lot more money in the end.
