brake seizing up

[01somta]

First off I should mention this is on my 2000 Chevy 1500 pickup w/ 110k miles. I noticed a couple months ago a buring metal smell (smelled like you where cutting or griding on metal) that got more frequent. I then noticed that going from a stop to a roll it felt like the front passenger brake was seizing, since the problem was intermitted I drove it a couple more days with no problems and but I noticed smoke coming from the rotor and what looked like hot molted pieces of brake pad dripping down on the wheel after parking the truck. I then took everything apart and replaced the caliper, front pads, new fluid, and had the rotors turned. Well today after 2k trouble free miles on the new setup I smell the burning smell again and see smoke coming front the fenderwell/rotor area. Could anyone please guide me to the next correct step before I have worse problems.

Thanks Dustin

I was thinking that it could be the soft line, the outside line show no wear but I guess there could be break down internally. If this was the case would the crappy line let fluid through under pressure but fail to release the fluid quickly and cause the pad to rub the rotor just long enough to cause problems?

That's a possibility. Are your caliper and pad slides clean and caliper slides lubed up properly? With the pads out of the caliper, you should be able to slide the caliper back and forth easily.

This definitely sounds like a caliper slider issue. The caliper should slide freely on the slider and be lubricated properly. A bent caliper anchor could also cause an issue with caliper movement.

Vegas brought up a good point to check, but do it by hand and not by using the brake pedal!

check your lines. I actually had a guy tell me something similiar. Eventually he changed the rubber lines and the problem was in the lines.

Slider pins are clean and well lubed. I will pull the pads and check to see how easily the caliper moves. Thanks guys for all the help.

try to compress the caliper if it's tight, open the bleeder. if it goes easily when you open the bleeder, then it's a bad hose. it's a common issue, the hose gets a loose flap inside that blocks fluid return.

It does sound like a collapsed hose. Feel the hose. It should be firm and not rubbery. Bend it around, sometimes you can actually feel the collapsed section. If it seems fine from an external inspection it may still be bad and they are pretty inexpensive. The roughest part is doing a beelding again. JR

With those kind of miles buy 2 new front hoses, and replace and rebleed.
Now why would it be hard to bleed? if your fast enough you wont loose toomuch fluid and heck if it has new caliper all it takes is gravity bleeding.
BUT replace both at same time.

[Apogee]

If your rubber hoses are failing, do yourself a favor and replace all of them at the same time as suggested above.

Check your hubs for loose wheel bearings. They shouldn't be bad this soon but check it out.
