    I wasn't sure if it was the master cylender or an abs problem

    I had the master cylinder changed but I still have the same problem. When the breaks fail I reapply the breaks and they work

That is Caused by a Faulty Brake Master Cylinder. Replace the Master Cylinder and this Problem will stop. Be aware, If you do this Job yourself you will need to Bleed the Entire Brake System for this to work Properly.

When I apply the brakes on my Dodge 2500 they sometimes push back and the ABS light comes on the dash, why?


You have a abs problem. Most likely a wheel speed sensor. Have system scanned for codes. The reason the pedal pushing back is system detected a skid. Brakes should work fine though

Why is it so hard to apply brake pedal?


_______power brake booster, check vacuum to booster and the check valve for brake booster. primary symtom is high hard pedal that requires greater then normal pedal pressure to stop car. testing booster= pump brakes several times with engine off to deplete stored vacuum. turn on engine with pushing slightly on brake pedal. you should be able to feel the pedal fade away a bit, and then become firm. But not hard. if you feel nothing at the pedal when engine starts. Brake booster is not working. Good-day! make sure vacuum is going to booster with engine running. it may just be a bad vacuum line or check valve.

2000 silverado feels like the brakes are stuck on and ABS light on


You may be right in that the brakes are applied.
The ABS would need to be checked for trouble codes to proceed.
You could also lift one wheel at a time to see if the brakes are on.

Acan you tell me why my brakes feel like they lift up when i start to slide on ice?? It is a town and country van, and it has some kind of traction setup, but im not sure what its called.


This is the feeling you get when ABS (anti lock brakes) sense a loss of traction. You'll feel almost like the pedal is pushing back against your foot. You may also notice a "humming" sound associated with this action.

When the system sense a slide it will alternately (very rapidly) apply then release pressure to the brakes, in an effort to slow the vehicle without sliding the tires.

I imagine you only notice this on very slippery surfaces, right?

From what I see in your description, there is nothing to worry about. If you continue to feel unsure about it, have a reputable local mechanic have a look at it.

Good luck!

Abs and trac off lights come on together but Intermitting


You have speed sensors that tell your computer what speed each wheel is going, and if one fails, this happens. The brake pulse is from the antilock brake system thinking a wheel is slipping.

ABS brakes not working


If you can feel the pedal pulsating and the light turns on the Abs is doin its job. if you want a better stop you could try a brake pad upgrade to ceramic pads and for even more stoping power add an after market drilled and sloted rotors.

You probably caused a short circuit when you changed the light. Change fuse #14. Next time, don't turn the lights on until you are finished changing the lights.
