98 chevy van 1500 brake pad smoke?

I bought a 98 conversion van (express/1500) at 123,000 miles. (6 months ago) The anti-lock brake light was on when i bought it. ( from a friend of a friend). My understanding is the brakes still would work, and worst case scenario, it wouldn't use the ABS. I was told the brakes were replaced one year earlier. The brakes worked fine.

Now at 136,000 miles.the pad indicators started scraping so I changed the brake pads. I started getting a burning smell, and thought the pads were just braking in.

However today, after about a 90 mile trip, I parked, and tons of smoke was coming off my front drivers side wheel. I almost started to think something was on fire but it wasn't. The wheel was hot, pouring water on it would make it sizzle and steam. The lug nuts were extra tight even after it cooled down. ( had to use a breaker bar, using my weight and my leg on the four way woudlnt' do it). I didn't even put them on extra tight when ichanged the pads 2 days ago.

I pulled the wheel and caliper for inspection. I found the pads seated correctly, but I found the piston side brake pad had a crack in it in the center of the pad, that seemed to go 1/4 to 1/2 inch deep into the pad. Also that my inside rotor felt like a couple of hills somewhat).

Because the piston was kind of hard to push back when i changed my pads the other day, I'm assuming the problem is a frozen caliper.

I just wanted to post here, and run it by you guys, and make sure i'm on the right track, and that it's not something else, like related to the ABS. I did a newsgroup search, saw one guy say the dealer told him the abs sensor went bad and the hub had to be replaced. He had a simliar sympom of a lot of smoke. Is my tough caliper movement related to the ABS light? probably not right?

Also in that post, he said the smoke was the bearing grease burning and the hub/abs sensor had to be replaced for a huge chunk of money. I'm hoping that's my problem?

Seems to me, the more likely problem is a frozen caliper... so I just wanted to run it by you guys for opinions?

  1. Is the cracked braking surface the cause of the problem, or result of a problem (caliper or "hilly" rotor feel)?

  1. Is the rotor on this model such that it has to be "dialed in" if it's removed? (i'm thinking with those hills it may need to be replaced or turned) ?

  2. as far as the caliper being hard to push back in, what's the best way to check if ti's frozen or not?

  1. I'm assumig I should return that crack brake pad for a replacement, right? or is it ok?

appreciate your time/help. TIA

90 miles with a stuck caliper could very well burn up a wheel bearing. I'd be more surprised if it didn't.

Very likely to be a frozen caliper with the possibility of extra collateral damage to the wheel bearing and rotor.

The crack came from being over heated by the frozen caliper.

The rotor was probably over heated also. I'd replace it.

See if it's hard to push back in. If it is, open the bleeder screw. If it still pushes back hard, the piston is seized, if it pushes back easier, there is another problem in the brake plumbing.

Yes, the pads need replacement. As far as returning it, the pad was not defective, it failed as a result of another part not functioning as it should. Or do you think that brake pad manufacturers should be held responsible for used parts and untrained service personnel?

New caliper, new rotor, new bearings, new inner wheel bearing seal, new brake hose both sides, thorough brake fluid flush before any new parts are installed, Bleeders open before pistons pushed in.

And then hope that when you shoved all the nasty shit in the caliper back up into the system the first brake job because you didnt open the bleedes first, it didnt cause this issue, other wise your looking at expesive antilock components. and then find out why the bloody warning light is on and get it fixed.

You did not mention the caliper slides. They need to be clean and lubricated for the caliper to work properly. Never push back the pistons without opening the bleeder screws. If you don't, you are pumping dirty fluid back into the ABS unit which will ruin it. Of course, yours is probably bad already.

The first thing you do when working on brakes is to flush the plumbing with new fluid and refill it. This gets most of the loose rust and dirt out so that it does not get into the master cylinder and ABS unit. Fluid needs to be changed every 3 years or so to get rid of accumulated moisture, thus preventing internal corrosion. If you do this, things like stuck pistons and ABS failures will become a thing of the past.

To all those who had negatives things to say: I dont' need to bad mouth or scorn you. Your compelled choice of words and attitude speak volumes for your own character, and your parents character (or ability to properly raise you to be a repectful human being).

I understand since you've been exposed to the proper procedure and information before I have, that gives you the right to not be understanding, to judge yourself as better than myself, and speak disrespectfully towards me. I really value and appreciate that. It proves to everyone here you are truly an honorable and knowledgable person with absolutely fantastic social skills, as educational teaching skills.

And now, I'd like to thank all the positive and informative replies to my inquiry. You are the positive force that makes the world enjoyable and worthwhile to live in, and share with. You are the brothers we can trust, and build relationships with, have good times and create good memories.

I appreciate your help, and the knowledge you've respectfully shared with me, that I can pass on to others. Karma has put a positive credit in your wallet. I hope those other negative (and possibly psychologically troubled) individuals will learn from your example.

Again, thanks a lot !!!!!! I REALLY do appreciate it!

gotta love the internet!!!

THANKS!!!!

You tackled a job you didn't know how to do properly with out researching it first. Then you drove the end results on the road with thousands of other unsuspecting soles. The bearings could have cooked to the point they failed resulting in the wheel locking up, and your making a pivot turn to that side at 60+ mph into what ever might have been beside you. The caliper seal could have melted to the point that it failed the end result you slamming into what ever was in front of you when the brake pedal hit the floor. The two areas of auto repair that can get people killed (usually innocent by standers) are brake repairs and suspension repairs. when they are done wrong, loss of vehicle control and accidents often result. The glory of the internet is having a place to go BEFORE you tackle the job.

Those that chastised you, you say have bad attitudes, and then you lay the karma BS lines out along with bad mouthing their parents. Perhaps yours should have taught you to not over reach your abilities, and to deeper consider the possible scenarios of your actions, and then perhaps none of this would be occurring now. I suppose if you had hit someone and injured them you would have chocked that up to karma too, bad karma on their part, they must have been bad in a former life and deserved what they got..

A vehicle that wont start is an inconvenience, one that wont stop is the grim reaper's delight.

A lot of people think Brakes, Not a big deal, do them myself. I'd rather they worked on the Motor then the Brakes. They screw up the Motor, the car isn't going anywhere, they screw up the brakes and their and others lives are in danger. Suspension also. I've seen so many BAD brake jobs done by others it's almost scary to think I'm driving around with those cars around me! It's bad enough when I see a car finally come in, Half of the vented rotor is GONE, so thin the brake pad came out and the piston is now grinding against the rotor. Brakes are Series Business. It's far more Important to be able to STOP then to get moving in the first place.

I see so many cars, Big piles of you know what, but they got their 24" wheels on their cars with rubber band tires. Of course they rub, but they put Space blocks into the coil spring to lift the car up higher. Scary what's out on the road. Add to that, Bad Drivers, Just today I had to back the persons car out for them, I mean really and it's not the first time. Add to that Cell Phones? I see it all the time, Weaving, driving strangely, and as I pass to get out of the way there I see the phone up to the ear chatting away.

So we have people driving around in cars that SHOULDN'T even be on the road. People that think they know how to fix their car and yet don't and also shouldn't be on the road. To be topped off with people that can't drive and even worse distracted that shouldn't be on the road.

With the exception of Anitlock issues, brakes are a nut and bolt job. If the DIYer gets the correct manual and reads the damn thing thoroughly, I dont have qualms with them doing routine brake jobs. Changing pads and shoes inst that hard a job. If you see something that doesnt make sense ask questions, dont make assumptions.

Even worse they cant hardly turn the steering wheel, which means they need a lane and a half to make a right turn, three shots at a parking space, and no way to avoid something if it requires hard turns.

Scary

Cell phone, automatic drop in speed, in the hammer lane at that, so they dont have to worry about rear ending some one. After two minutes the car starts weaving slightly with in the lane, progressivly getting worse as the conversation continues untill they hit the the shoulder or the lane reflectors which snap them back to attention, then it starts all over again untill the conversation ends. I drove truck for a number of years. cell phone users scare me more than Grandpa in his RV, the one he bought as big as a greyhound bus and is allowed to drive with no training after driving nothing bigger than a VW bug all his life.

Scary that too many states dont have inspection laws. want to be really scared come to florida. No inspections, and the cops wont do a thing if you call them . In Texas I could pull the tags and make the owner get a tow truck if he didnt want to fix a safety issue. In NY all I had to do was call the State Troopers.
