In some dry climates the brakes do squeek alittle but normally if all caliper slides are greased , rears are often not as the pins are on the bracket portion, and the pads all have anti squeal shims or permatex applied to the pad rears, nothing is heard. If from a saltly area then under the metal shims that the pads ride on can get rusted and the pads actually stick against the rotors and make noise. So, bottom line, if they did a complete brake job they should not make noise except a rare few times from dirt/mud if off roading.

brakes grab as if on ice by tamofaye

I have a 98 Chevy Cavalier. The pads and rotors have been checked and are fine. Sometimes when I apply my brakes it's as if they are trying to grab and it's like how my car drives when I try to stop it on ice. There is no pulsating in the pedal and the ABS light does not come on. It usually happens when I'm going fairly slow (like pulling out of a parking lot and pausing to check for oncoming cars) and almost always happens when I'm pausing and I'm on a somewhat downward incline in the front. The grabbing is taking place in the front and not the rear. The brake fluid needs to be topped off but other than that, that is the only problem anyone can see.

Yes a Chevy but not a Blazer/Jimmy so generically could be many things as ABS system, master cylinder, sticking calipers (grease slides) but an easy thing is to bleed the fronts until clean fluid comes out and see if this solves - could have crap in there - a shop or you can do this and check the system out. Did you pull the rotors off and the calipers and check all cause a simple visual will not tell much.

Update intermittent brake problem by crpntrlady

After 3 1/2 months, my mechanic sent my jimmy to a friend of his who had a different type of scanner. They believe the problem is the Right front wheel bearing speed sensor, does that sound possible to anyone?

Yes, that is what pulses so the ABS knows the speeds on each front wheel. Dealer would have picked that up first time.

Rear Rotor removal 2002 Blazer by cact34y

New to this, hope this posts OK.
 
Looking for advice on removing the rear rotors on a 2002 Chevy Blazer, 4WD. I suspect that the emergency brake pads are holding the rotor on.
 
My assumtion is this is a combination rotor / drum design and there is a small ridge that the internal pads are catching as I try to remove the rotor.
 
Can anyone confirm and offer advice?
 
Thanks

Doubt it - those little shoes rarely ever hang up and not like a total rear brake - no ridge forms on a parking only shoe in the drum. So, if as most the rotor/drum has rusted to the axle flange so get a 3 lb hand sledge and wack it a few times - I bought a special dead hit hammer at Sears that is shot filled and plastic coated ends so I can hit away on many parts on the Blazer that require some help coming off. Really thats all you need to do and may take a bunch of hard blows to get off - hit the center and sides but be careful on the rotor face. I would also suggest getting rebuilt calipers cause those ones in the rear always bind after pushing back in for new pads and make sure you pull the slide pins out of the bracket and grease them (a rubber cap holds on and it just pops off). You can get "loaded" calipers with the pads, caliper and braclet all ready to go for about $60 per wheel - cheapest way to go if a slide is frozen.

Thanks! I'll give it a try.
 
The rotor does move outward a little (maybe an 1/8") and then hangs up. That's why I thought it must be catching on the pad inside. It even sounds like something inside is catching. The lug holes move in comparison to the lug bolts so it seems to be moving in relation to the hub itself.
 
I didn't see any clips on the lugs. I'm in the northeast so the first thing that came to me was a ridge at the edge of the inside of the rotor / drum caused by some corrosion or wear. Will try the old way, get a bigger hammer

Originals did have I believe clips on 2 lugs and I did assume you have the caliper bracket OFF and the parking brake released and the cable/pedal is not over tighten.
Then hit away. The axle will move in the housing some - its a GM.
