Breaking issues plz help this is my D/D!!!!

Ok I bought this truck back in May as a bday present to myself and there was already an issue with the ds caliper engaging late and causing the truck to pull to the left. So no big deal I would just replace the caliper and that should fix the problem. I havent gotten around to doing that yet, but my issues that I am havnig now has gotten worse. When I am driving the truck and hit the brake to slow down the brakes work just fine but, when I start taking off again I can feel the front brakes are still grabbing and will not release until I hit the brake a few more times. This in turn is causing the truck to bounce and skip when I'm driving. Any advice or suggestions to what I need to do is much appreciated.

Yup, it's doing more than just "making the truck bounce and skip" it is burning up the rotors as well. Sounds like the piston is not retracting properly. Get that caliper changed out quick, and you make stronly consider doing the other side as well. Check the rotors as well. If they are warped or grooved you need to be replacing them too. Call it an early Christmas present to yourselft.

Yeah I figured that it was causing the rotors to get hot becuase you can smell that "burnt" smell when its happening and its also causing me to have to push the gas down alil more than normal to get the truck to take off. Is there any other Issues that could possibly cause this to happen? I just want to make sure that I have every base covered so I dont give someone in front of me a new rear end lift.

Don't wait so long if you have brake issues... May to October is too long.
I'd change both calipers and pads, check the rotors.

Re: Breaking issues plz help this is my D/D!!!!

I would just do the whole mess. I used to get rotors turned and try and save the calipers. Now on the front I replace all of it. Its not that expensive anyway. Look at the cost of calipers, rotors, pads, hoses as cheaper than an accident.

I totally agree. lol I just called auto zone oreillys and advanced auto parts and all of them want these codes to make sure that i buy the correct parts. One wanted me to measure the back drum brakes just to get the size for the front rotors. Im about to pull my hair out, and I cant tear into them until this weekend.

Yes!
If it's pulling to the left,... the right hose is collapsed.
Change them both.

Re: Breaking issues plz help this is my D/D!!!!

^^^ Ditto could be caliper hoses collapsing, I would replace those too.

What year is the truck? 2wd or 4wd?
1/2 or 3/4 ton.

If it's 2wd 1/2 ton then only choices should 1 inch or 1 1/4 inch rotors.

Should be a RPO list in the glove compartment. JB3, JB5, JB6, & JB7 should be the choices, You should be able to order any brake part you need with this code.

Re: Breaking issues plz help this is my D/D!!!!

ive also seen it happen a time or two when brakes are sticking and people keep driving them they heat up the grease in the bearing to the point that it leaks out which in turn takes out the wheel bearings

Re: Breaking issues plz help this is my D/D!!!!

I usually get loaded calipers, rotors, and hoses online from RockAuto Loaded calipers come with pads and hardware usually including guide pins. You can get the real cheap stuff... But... Raybestos or Wagner loaded should be around $40-$60 a caliper with the core charge. Good rotors are pretty cheap and quality name-brand hoses are usually right around $10.

I usually flush the whole system, with fresh fluid from an unopened bottle, till it runs clean out the front and back bleeders. It cuts down on the water and internal rust.

TRW and Moog used to be good names in ball joints. IDK anymore. I think they're all made in Asia or India now.

Re: Breaking issues plz help this is my D/D!!!!

Here's the brake system release chart for an '87, for reference:



One of the things you could do is look for a code on the brake vacuum booster, which would help distinguish which brake system (JB3 = "CH" vs JB5 = "FD") that you have.

Bottom line, though, is we build very very few JB3s. If you simply guessed JB5 you would likely be right.

J50 just means Power assisted brakes, If JB3 is the base brake system, It may not get listed, Maybe Keith will chime in on this.

Like stated you may need to just measure the rotor thickness.

Re: Breaking issues plz help this is my D/D!!!!

Lol and you think that you getting in new vehicle is not going to have critical parts issues to? your taking just as much risk that I am. I didnt say I didnt know how to fix them, but again you started this all. When i baught the truck the brakes were not bad and the truck drove and brakes beautifully
No ones feelings were hurt. You assumed that i kept driving the truck with the issues that it was since i started this thread.
