Question about 2001 Dodge Ram 3500 Truck

Brake pedal stuck down

I was replacing brake master cyclinder on 2001 dodge ram 3500. When I pumped brakes the pedal is stuck in down position on floor & won't release. It feels like it is catching up in the hydro boost assembly. Any suggestions?

Pull the pedal back up as the problem is air in the system. You may have to do this until the air starts to move out of the system. IT would be advisable to prime the master cylinder before fitting it as this overcomes the problem of trying to get the cylinder to pump up.

SOURCE: 2001 RAM 2500 Brake Pedal Goes to Floor

Excessive runout or wobble in a disc (Rotor) can increase pedal travel due to piston knockback and increase piston seal wear due to necessity of caliper to follow disc wobble. Thickness variation in a disc can also result in pedal pulsation, chatter and surge due to variation in brake output when disc section is uneven. Dishing or distortion can be caused by extreme heat and abuse of the brakes. Hope this helps, Good luck.

I would guess the brake fuse ( this does not use the same fuse as the tail lights/blinkers) or the ground for the brake light bulb.

SOURCE: Brake pedal all the way to the floor...Possible abs module?

Im going to assume that a mechanic has already checked for the most simple causes like making sure the brakes have been bled. If the abs module is faulty it will default to just a no abs state, but that wont cause the pedal to go all the way to the floor. I agree that replacing the caliper is probably gonna fix the problem, but I might try to bleed the brakes first and see if that solves it first...

Was the brake system bled after the master cylinder was installed?

After anyh brake work is performed, particularly with disk brakes, you have to pump the system up to get the calipers reset. Start engine, pump the brake pedal several times, and you will begin to feel the brakes come back up, assuming everything else has been properly repaired.

Let me know what you find.
