Question about 1999 Pontiac Grand Am GT

Caliper crunch Any time i push the brake in i hear something that sounds like the caliper is making a crunchy sound. pads are new, but im worried it might be the piston boots that are dry or other.. the sound is surely coming from the calipers though, ive triple checked this. Any ideas? Other issues/Info: Brake light is on, ABS and trackion control is automatticly shuting off. When coming to a stop, there are no other issues besides the crunch (which can be felt through the pedel). No warps in the disk. car does come to a full stop with a deep pedel push for sudden stops, but normal push for normal stops. i have been able to lock up the brakes on stops. i do believe these are the original calipers (bought car from family member). The master cyclinder might be needing replacement.

I have the same issue with my car. We have had the Calipers and brakes replaced. The whole system has been flushed, we have made sure there wasn't air anywhere. We have replaced the entire ABS/Master cylinder to no avail. The car has issues until the abs fails and the light comes on, once that happens the brakes work fine. We have had the car scanned several times and nothing.

Make sure the pads are installed correctly. There is an inner and an outer. make sure the hardware is lubricated with some brake lube. For the ABS/Traction lights, you will need a scan tool to find out what is going on.

2007 ford sport trac new brakes hear a clicking coming from brake caliper when stopping can i just bleed them or is it going bad? disk front and back

If the brakes are making a clicking sound when the brake is applied, that means that something may not have been put back together right. I would definitely yank it back apart and check to make sure that the brake pads fit securely in the brackets with no play at all, too. It's easy to get the wrong pads for a Sport Trac; the parts are completely unique and a lot of parts stores even have incorrect listings for brake and suspension parts for those things. Brake system wear can create a grinding, pulsing, or squealing sound, but shouldn't produce a click. Something isn't right there!

I have a 2000 Alero and have front wheel drive. My front left tire will rotate to go forward but as soon as I put the car in reverse the tire will rotate a little bit but than stops and drags with the car....

Sounds like a brake issue to me, like the caliper sticking. I've taken the axle, brakes and hub/wheel assemblies off these many times, pretty simple. If you choose to DIY, I would suggest you buy a Haynes manual....about $20 well worth the investment. The crunching sound maybe a damaged pad, or something that got lodged in there. You have my curiosity, wish I could see it for myself! :) If you aren't a DIYer, take it to a place that does free brake checks, I suspect you may possibly need a new caliper.

The sound you hear is most likely the brake pad wear, not the caliper. When pads start to wear down, they will start to make grinding noise,and not necessarly all the time. As the pad wears down more, then the grinding will be hear consistently.
It could also be a worn hub bearing. Jack up the vehicle and spin the tire and see if you can recreate this noise. Use jack stands to support the vehicle.

Front right tire makes a grinding noise , hub assembly has been replace problem stills there, what will be the problem?

It could be a lemon replacement hub or it could actually be the tire. Check the tires tread for irregular wear patterns. If the hub was loose prior to change this could easily cause the tire to wear in a "choppy" fashion which can also cause a rough humming sound that I have often heard customers refer to as a grinding sound.

After replacing front roters and pads - I have

It sounds like the calipers have seized after being pushed back to allow for the new pads. Take ot the new pads press the brake pedle slowly to release the caliper(just enough so it's released almost to full , then push back with your finghr and thumb) one side at a time, coat with copper slip and do the same on the other side. Rgarding the abs, make sure the new pads have the correct electrical connections to complete the abs circut, if not you will have to buy new ones that do. Hope that works

Sounds like the caliper on the side that isn't wearing is not working properly. You need to test it to make sure that it is pushing out properly when the brakes are pressed. I can't imagine that it is working correctly. It sounds like the piston isn't moving out and you need to look at replacing that caliper so that your brakes wear evenly and also to make sure you have your full stopping power. Good luck and thanks for using FixYa!

either you have a caliper that has locked up and worn brakes down or it is just the metal that is in your pads making that noise. does it pull to either side when driving?
