I have tried everything. I changed the brake pads, pasengers side caliper (it was craked) I even bled all the lines well the ones I could get fluid to come out of. I took the Master Cylinder Resivor off of the master cylinder to check that, dumped out the brake fluid and there was black stuff in it. I don't understand why my brakes worked before I changed them and now I have no brakes at all brake pedal goes all the way to the floor. I am not sure if it is the master cylinder (hope not) or maybe the hydralics is clogged or somthing. I have been at this now for 3 days baffled. PLEASE HELP!! Thanks in advance.

I have tried bleeding them again and the only place I can get any fluid is at the Hydralics bleeder. There is simply NO fluid coming out of the bleeder valves. I am going in this sequence, LR, RR, LF, RF which is furthest from the master cylinder to the closest. If I am doing it wrong please let me know so I can bleed them corectlly!! Thanks again

1. you need another person to help you.
2. check the master and make sure that its full.
3. when you bleed the brakes have the helper to first pump the brakes 12-20 times repeatly than hold the pedal firmly before you open the bleeder screw on the calipers. You need to do all 4 wheels the same.
4. As you open the bleeder tell the helper to force the pedal all the way to the floor full force and hold it there til you close the bleeder before the help releases the brake pedal.
You must do all 4 wheels one at a time. left front, RT front, Left Rear, Right Rear.
5. Now check the brake fluid resrevior and refill it.
Repeat the Steps again.
YOU should Have the MOTOR RUNNING TO allow the power brakes to work like they should off the vaccum when your bleeding them.

well, I'm assuming it's not really a 3.25 ton....maybe a 3/4 ton like a ram2500.....your problem is not really that complected...either you have installed the wrong side caliper on the side you replaced..the bleeder should be at the top, its also important that you replaced the caliper with the same piston type (either steel or phenolic). If that's not the problem your bleeding in the wrong sequence....or there is a leak and your losing fluid, or the master is bad (problem not likely)...why you took off the reservoir i don't know but that was BAD...OR AND THIS WOULD BE REALLY BAD...you didn't put brake fluid in the system..if you used something other than brake fluid every thing that has rubber in it will have to be replaced..master, calipers, hoses wheel cylinders etc.......you best solution would be take it to a qualified mechanic

I am afraid that when you removed the reservoir on the master cylinder you probably introduced some air into the system. Brakes work by pushing brake fluid through the system and the brake fluid cannot be compressed, but air can be. Accordingly, when you push down the pedal, the air compresses and the brakes do not work. You will likely have to bleed all of the brake lines to address this.

When you removed your master cylinder you induced air into your system, you should have your brake system flushed by a professional, possibly bench bleed your master cylinder as well to get the air completely out. the reason
I reccomend the flush is it is considerably cheaper than changing your master cylinder, and it will ensure there is no air in the lines, and also clean the lines out of any debris. most brake system flushes run about 20-40 USD, at least around here.

Sounds like you have air in the system. Only thing to do is bleed the brakes properly.
If you don't have someone to help you, you will probably need to take it to a mechanic.
