About two weeks ago, I had a master cylinder replaced on my 1991 Dodge Ram (stick shift). Since then, our brakes have needed to be pumped and sometimes the brake pedal goes all the way to the floor. Today, my husband was driving down a hill and braked. The brakes went out and he went into a ditch. The brakes are not working at the level they were before the new master cylinder was put on. In fact, the brakes were fine before. Any ideas on what is going on? Is the mechanic responsible for the problem and its eventual repair?

Ok if the breaks are not working the I have to ask did the guy that installed the master pre bleed it befor installing it.
When you put on a master cylinder you have to blead out all the air out befor installing it. If all thy did was put it on and not bleed it you now have a lot of aid in the breaks.

My advice take it back to that place and complain. Tell them thy did not pre bleed it and installed it improperty. That now the hole breaking system must be bleed and then the breaks will work.

the master brake cylinder either needs to be replaced again or the mic didn't bleed the brakes to get all the air outta the lines. also check the master brake cylinder reservoir and see if it has any fluid in it. and put some in also park somewhere and then pump brakes see if it is leaking anywhere.make sure you put cap on after you fill it then check after pumping the brakes. also has hubby heard of emergency brake?? it is also called parking brake. it is a mechanical brake that works via cables to the rear brakes. have him learn to use it. hell a brain would help too

Here is the test.....Pump the brake pedal until it stops near the top...Then, keep applying steady pressure. If the pedal slowly moves down, with the pressure, check for a leak. If there is no leak, then your master cylinder is faulty. If it stays near the top, then there is air in the lines, and all 4 wheels should be bled individually.

its either a bad master cylinder. or they didnt bleed it right, sounds like air is in the master cylinder take it back to the shop and have them rebleed it if that dont work then they need to put a new master cylinder on it.
