Alright I have a strange brake problem. When I turn on my truck anytime and start to drive and hit the brakes it pulls HARD to the right and sometimes the left. They dont work real well ALOT of pressure in the pedal. But right when the brake light and ABS light come on they work great. Usually takes a minute or two. Also if I lock up the brakes to come to a stop the back tires lock up like my ABS is not working.

 

abs sensor issue? I would make sure they are all clean.

otherwise check out the front and rear brakes. see if something is stuck or messed up

 

I dont think its the sensor for some reason. I wonder if I disable the ABS if the brakes will work fine just to see if its that.

 

I had something similar on my '04... The rear brakes were sticking and would sometimes lock up, or would cause me to have almost no brakes at all. When I took the drums off, the pads just fell out because they had cracked due to overheating...

 

I am going to replace the rear shoes Friday thanks for your input. Man 87K miles and I have NEVER opened them up this is going to be crazy.
