Ok so heres whats going on, I had a problem with the drivers front brake caliper would stick and lock the front wheel it wouldnt release. untill I bleed fluid from the bleeder.
I thought it was a faulty caliper so I bought new calipers, rotors, brake pads for the front brakes on both sides. bleed the calipers in installed everthing
took it for a test drive and the drivers side locked up again. it will not unlock till I bleed the fluid off.. ABS light is on too...
any Help..:-

 

You need to pull the abs codes. It could have an isolation solenoid sticking closed.

 

Your brake line is swelled and letting hydraulic pressure past but holding it in. Sounds like a bad brake line. As for ABS I have no idea.

 

Thanks I will have to get ahold of a buddy who has a scanner tool to pull codes from a diesel.
thats what it lookes like to me the pressure activates the brakes but wont release the pressure..

 

does any one have a chart on how the brakes work, or how the abs unit works.

 

It's not a chart but a service manual that PaysonPSD (Robin) shared on this site. I presume that since you could have found it by doing a search I can share it.

Thanks PaysonPSD, I've used this info numerous times in just the past few weeks.

Thanks Tiny wonder,
I guess I could have done that.. Anyway found the problem. I had taken off my shock hoops & shocks to re polish nthe bodies and re coat them with clear. when I re installed them the shock resivor was too close and pinched off the rubber brake line, thus allowing pressurized fluid to apply the brake but not return. and one of the wheel abs line was also pinched that caused the abs light.

Thanks to all the responded with the great Ideas.

It was Camodown who came up with a faulty rubber brake hose that got me too look closer at them.
