Two problems related to brake master cylinder have been reported for the 2000 Dodge Ram 1500. The most recently reported issues are listed below.
I went to change my front pads (for the 3rd time in 15 months) and noticed that yet again, one of my calipers was stuck and one of the piston diaphrams was torn. I replaced the caliper, put in my new pads, bled the system, and my brake pedal goes all the way to the floor, the vehicle is driveable, but my stopping distance has greatly reduced. I have to pump the pedal 2-3 times for the brakes to grab. If I stab on them, them pedal will travel all the way to the floor and then the rear wheels will lock up and the front brakes dont work at all. I replaced the master cylinder and the problem still persists. Dealership has absolutely no idea what the problem could be, and niether do any of the local shops.
2000 Dodge Ram 1500 -Dec 2009 - 47000 mile. No indication of brake issues until hitting them hard to avoid car that ran a red light. Brake line from master cylinder to rwal unit failed (pinhole leak), but managed to avoid collision. Drove home (slowly) and fabricated/installed replacement section (about 16" long). After bleeding brakes - drove truck normally until June 2010. Then, with no warning, the brakes again failed in a parking lot stop. Found the leak in the rear section of the line running from front to rear. Dealer estimate to replace all hard lines is $1000. Who can afford that ?? so, I will be spending many hours of my own time to fix the problem caused by cheap imported chinese steel. Thanks bill clinton !! I have other "good american cars" that are 40+ years old and 100k+ miles with the oem lines still good. These new vehicles suck !!!.
