I can't see much from here. Any abs codes/ antilock brakes. Did you follow proper bleeding procedure?

Can you get any fluid at the wheel cylinders?

Were you having this problem before you worked on it? With vehicle moving slowly will the brakes stop the vehicle? What about your brake booster?

I had brakes before the line broke, so I replace all lines then I replaced the master but I have a peddle when the car is off but when I start it up I have no pedal? Anything you can think of what might cause it to do this would greatly help me.

Hi, I asked the boss to have one of the others check out your post. I've gone about as far as I can. I'm not sure how long it will take to get a reply.

Hi checking into this a few questions. When you first installed the master cylinder did you bench bleed it before install? Is this the correct master like if it's for a vacuum booster and you have ahydro boost the may be different with different lengths of rod. If you bled this correctly, meaning rr-lr-rf-lf it should be ok unless the rod is to short. If this is hydro boost then you may still have air in system. If this is a vacuum booster then seeif the check valve at booster is leaking.

Oneother thing, if this is hydro boost check for full p/s resevoir then do this: BLEEDING HYDRO BOOST SYSTEM

1. Fill power steering pump reservoir and leave undisturbed for at least 2 minutes. Start engine and run momentarily. Add fluid if necessary. Repeat until fluid level remains constant with engine running.
2. Stop engine. Raise front wheels off the ground. Turn steering wheel from stop to stop. Add fluid if necessary. Lower vehicle.
3. Start engine. Press brake pedal several times while turning steering wheel from stop to stop. Turn engine off. Press brake pedal several times to exhaust accumulator pressure. Check fluid level. Add fluid (if
necessary).
4. If fluid is foamy, let vehicle stand for several minutes, then repeat step 3). Air in system will cause fluid level to rise with engine off. Continue to bleed system until all air is expelled. If all air is not expelled after
bleeding system, check power steering system for problem.
