Question about 2003 Chevrolet Avalanche

2 Answers

2003 Avalanche--front brakes make a pulsating/grinding sound when applied while on wet pavement. Doesn't stop vehicle very well. I replaced the wheel/hub bearing assembly on both sides and the rotors and pads. The wires are plugged in correctly and no loose bolts are found. Could it be air in brake line. Fluid is full.

Sometimes you can get a bad rotor. You can measure the rotors with a micrometer.
When you took off the old rotor did you take a wire brush to the hub to make sure to remove any debris/rust so that the new rotor(s) sit nice and flush on the hub? What causes brakes to pulsate right after rotor and pad replacement

Not to question your ability, if you listen from the drivers seat while driving, just do yourself a favor, check the rear brakes, funny how sound travels and tricks the mind

SOURCE: Brake pedal pulsates when appling brakes

If the new rotors were not allow to seat after replacement they will warp extremely easily. Easy to check. Remove wheel and check for trueness of rotor, a dead give away is if you see a blueish tint on the rotor.

It is pretty easy, there is not much labor involved if it has anti-lock brakes in the rear you will also have to un-plug the wire harness attached to hubs.

Yes the bearings can be changed on this truck. The bearing races will need to be removed from the rotor to do this use a punch and hammer once the rotor is removed. You will need inner bearing and race, outer bearing and race, and a seal, plus grease to pack the bearings. The hub on these trucks is the rotor. Please rate.

SOURCE: 2004 avalanche wheel bearing hub assembly will not

If ALL bolts are out....hit it with a sledge hammer to loosen it if necessary.
Side hits should do it.
Make sure you have the correct replacement because the old one will be no good after hitting it to remove it.

I have an 08 Avalanche. Having a severe grinding noise when coming to a stop in front. My brake pads are fairly new. Just started on Thursday. Sounds horrible now. What could it be.


Hi Benjamin:
I'd be getting the brakes checked (or actually check them myself).
That involves getting the vehicle jacked up, removing the wheels, and visually inspecting the brake pads and discs.
PLEASE! This is a safety issue and you NEED good brakes.

Don't delay/ Get them checked.
Best to you.

Check your disc brake pads to see if they are down to the wear indicaters. When brakes are worn it creates a metal on metal grinding sound when vehicle picks up speed but will intermittenly stop when pressure is applied to brakes. Note that front brakes will be replaced 2 to 3 times more often than back brakes due to the front brakes being your primary souce of stopping power.

Rear wheels dont turn when i put van in drive. just drag on pavement. front wheel drive (2003, pontiac montana)


Sounds like someone has applied emergency brake, and it has not released for one reason or another. try applying e-brake, just until you feel it resist, then go another inch or so and release it. Keep trying to see if it will let go. Perhaps putting vehicle in neutral and try rocking it backwards will help also.

Anti-lock brakes activate on dry pavement


First, is the ABS light on? Does it come on when it's doing it? Make sure the brake fluid is full, and the brakes are still servicable, ie, pads still have meat on them. If so, the abs control module or a speed sensor might be on the way out. This is a safety issue, and I would recommend getting the truck to a good mechanic to have it checked out.

from my experience its sounds like ur front rotors may need resurfaceing...if ur doing that...may as well replace the brakes on the front as well...sometimes glazed front brake pads may make a sound but never heard of it as a grind, usually its a squeal...have ur dealer check ur rotors for hot spots in which u would need them replaced if they are overheated..also check the front pads for cracked brake pad material
