Front hub bearing. If you were the one who replaced the pads you should have turned the hub while the caliper was off and checked for roughness or wobble. Imagine the rotor wandering from side to side and rubbing the pads; thats what a worn hub will do.

My 2004 gmc denali makes a grinding / clunking noise in the rear left side only when going over bumps in the road. Then the abs light and traction light flashes on then back off. It only makes the noise...


Check the abs sensor on that wheel and it's wiring. It sits very close to brake disk and could be loose or fouls by dirt and corrosion. Easy to replace.

Front end clunking noise


Take the brakes apart & clean up all rust,check everything out
& lube things when putting back together
Have to do that at least once a year

Don't need machining every year or new pads, but have to knock
down the edge on the rotors & get rid of rust & lube (anti-seize on
everything but inside the caliper slide bolts, there you use the synthetic caliper lube

The clunk could be worn drive axle joints or drive shaft joints
or shocks
When your on the brakes or hit bumps your loading things differently & the clunk goes away

2003 Chevy Silverado is making a clunking noise, on and off sometime over bumps. Also a deep grinding type noise in the same location while driving not constant


Hello Karla,

It sounds like you may have a bearing or CV joint going out. Your vehicle will need to be jacked up and inspected. It may be more than one problem too. Its possible the dragging noise could be something between brake pads and rotor, but the grinding that comes and goes in reference to direction sounds like a bearing or joint. I would take it to a professional right away and ask for an estimate only, and then get other estimates from other shops as well. Good luck to you.

Why are my brakes locking up and grinding whenever i hit a bump or uneven surface while braking?


Sounds like you have a speed sensor signal dropping out. This would cause the ABS system to falsely think one of the wheels has locked up and would turn on the abs to unlock the wheel.

You can visually check the wiring harnesses to the speed sensors to see if there are any corroded connections, corroded wires or broken wires. If everything looks good than the next step would be to drive it with a scan tool and watch ABS data. You should be able to spot the speed sensors that drops out on the scan tool when the problem occurs. Than you can focus on that wheel to see what the problem is.

My 2009 Toyota RAV4 (4WD) had been sitting in garage for about 3 weeks. Started fine but didn't want to move forward or back and then the electronic stability light would flash after a couple of seconds....


sounds like the handbrake had stuck on.
the brake shoes can bind if the handbrake is left on and this is probably the clunk noise.
you are almost certainly right about the "cleaning themselves"
if you look at the disk surface after a few weeks parked up you will probably see it is a little "rusty" .

if you are leaving a car for more than a week or so, you should release the handbrake first.
either leave it in park as this will lock the gearbox rather than the wheels, or chock the wheels.
that way the pads will not bind to the disks/drums. you may still have the grinding noise as the light rust on the surface is removed.

My BRAKE light came on and I thought it was my parking brake


Rubbing noise usually indicates that your brake pads has worn down, and it's rubbing against brake rotor. It's more like grinding noise rather than rubbing, right? And for the brake light problem, as brake pads wear down, brake fluid level goes down too. Your car is equiped with a brake fluid level sensor. So, check your brake pad first before adding brake fluid.

Anti lock light came on


You have a serious brake problem, most likely the front brakes are metal to metal, have it inspected ASAP, many brake shops and tire stores do this for free.
