NJK66 OP super street N Joined: Jul 2003 Posts: 231 Michigan	I have a 1997 Dodge Stratus that was given to me. It has 50,000 miles but has been sitting for 4 years. The brake pads were frozen to the calipers so I decided to be safe and replaced everything front and rear. 1) Front - Rotors, calipers, brake pads 2) Rear - Drums, brake shoes, hardware kit, left and right rubber brake lines, right and left wheel cylinders 3) Master cylinder. My problem is I cannot get a brake pedal. I have bled the heck out of them and still no pedal. The rear brakes are adjusted properly. Am I missing something?? Any advice would be a great help. Thanks

Not familiar w ABS. If good hookup the front discs and bleed them out. live every 24 hour block of time like it's your last day on earth

Thanks what order are you bleeding? I think that system is diagonally split. If so, you need to bleed LR, RF, RR then LF instead of the usual RR,LR,RF,LF.

The car does not have ABS. I bled the M/C first then the RR LR RF LF. I have been wrenching on cars for a long time and I have never encountered a bleeding problem like this. I probably have been bleeding 4 times the normal time to bleed a set of brakes. I remember an 1984 Dodge mini-van rears was a toughie but it eventually bled. I will try pluggind up the M/C. Potentially bad because it is a rebuild.

My error was I put them on the wrong side and the bleeder screw was sitting in a position where air was trapped in the top of the caliper. So, I could have bled til doomsday and never got any pedal. Switch calipers side to side and the bleeder was an inch higher and no air was trapped in the top. They bled out perfect and now have a nice firm pedal. Thanks to all who replied.

It's not like a bleeder screw was on the bottom live every 24 hour block of time like it's your last day on earth
