I have a 2000 Dodge RAM 1500 4x4

I have replaced both front rotors,calipers, brakes, both rear cylinders and brakes and also the brake line that supplies fluid to the back brakes. I have bled all the brake cylinders from rear to front and everytime I start the engine and the power assist kicks in the brakes go to the floor.
Is there something that I am missing or omitted from the bleeding process?

 

You bled clockwise starting at the left rear? How about making sure there's enough fluid when you bleed?

 

Yes, I started from the farthest most point from the master cylinder and worked my way to the nearest. I checked the brake fluid after bleeding every cylinder.

This all started when I replaced the front brakes and calipers on a routine brake job. I drove around the block to test the brakes and all was fine. the next day I got in the truck and I pushed on the brakes and the pedal went to the floor, this is when I noticed brake fluid gushing from the brake line that supplies fluid to the rear brakes. I purchased the brake line and installed it. This time I decided to replace the rear brakes and cylinders as well.
When you pump the brakes with the engine off the brakes tighten after 2-3 pumps, but once you turn on the engine the pedal drops to the floor.

 

i am having this very same problem, did anyone ever find a solution?

 

I had the same problem whenI had to replace my rear line.Bleed brakes start it up and they went to the floor Then I bleed the brakes with truck running and that took care of it..

 

yeah i second that starter up and do it.

 

Not breakin *****, but doesn't bleeding start at the right rear?

Good luck with your ride.

 

I third the starting of the truck to bleed that much line. I did this twice in my POS mazda pickup when I blew out 2 rear axles and had to replace them.

 

That's how I was taught many years ago by an old independant mechanic.If the vehicle has power assisted brakes, then bleed them using the power assist.

 

Hey all:

So, yeah I'm an idiot.I replaced the hard brake line as it rusted through. I work off of All Data (available through the local library). I can't figure out where the bleeder valve is located. All Data didn't provide pictures and I don't know anyone locally that can show me. Can anyone help?
