Assumeing you have no big leaks in the new brake lines witch you would see because there would brake fluid all over the ground I would say you didn;t bench bleed the new master cylinder There is air in this part when you buy it and you need to get it out before it will work Heres how you do it first you need a kit it consests of plugs that you screw into the holes that the brake lines go into but they have fittings for hoses to plug on to them you put the master cylinder into a vice screw the plugs into the holes put the hoses on the fittings and put the other end of the little hoses into the cylinder resivior fill the resiviors with brake fluid then take some kind of a tool i like to use a 6 inch 3/8 ths socket extentoin because not sharp but you could use a screw driver And push the piotion in from the back of the unit repeataly until you see now more air bubbles coming out of the two little hoses that are in the resiviors like ten or so pushes Then reinstall hook up the lines and bleed at wheel cylinders with wheel cylinder bleeding always start at the fertist wheel and work your way back to the closetes wheel Its not as hard as it may sound good luck

How do I fix the brakes in my 99 Toyota Corolla? I have no brakes and the pedal goes right to the floor.


have you adjusted the rear brakes correctly ( drum brakes)
if not drums then you have air in the systems still
brake bleeding is done starting at the wheel with the longest line and ending at the shortest line
It is a 2 person operation unless you have a pressure bleeder pump attached to the reservoir
your problem is air in the system

I have a 1994 bonneville that you have to push brake pedal to floor and fluid empties within 1 day. Is it the master cylinder or the line?


check all brake lines and wheel cylinders for leakage. if no leaks its probably the master cylinder. symtoms are-- pedal will sink to floor when stopping or not. or master cylinder leaks from behind "it", and runs down brake booster. if booster goes bad the pedal will be very hard! good-day !

We changed the pads, rotors, drums and shoes on our 2001 montana, after we were done the break pedal goes to the floor, we were told to change the master cylinder and did,, but it didnt fix the problem,...


After you change brakes you need to bleed air from the brake lines what you need to do is find the bleeder valve its usually rite beside where the brake line goes in the calipers and looks like a grease fitting get someone to pump the brake pedal 3 or 4 times and hold it while someone else loosens the bleeder valve to drain the air out keep the pedal mashed until you get the bleeder valve tightend back up . Do each wheel until fluid comes out check brake fluid while doing this so it doesnt run out. Hope this helps

Is the master cylinder good? a bad master can cause this also did you bleed the master first before bleeding at the wheel and also make sure the bleeder screw is clean, if the hose is good then theres only a few things, a bad master or a master that wasnt bleed, try bleeding the master first then try rebleeding the brakes.

When you bleed the brakes are you starting with brake furthest from the master cylinder? Also was the master cylinder bench bled? If everything there is okay and you are not getting any air in fluid stream, you could try bleeding the brakes by having some one slowly pump the pedal till it is firm. Then have them let off open first bleeder valve and slowly depress to floor and hold there untol the valve is closed. repeat this at all bleeders. You may want to have car running to do this. Try this and let me know.

1998 chevy s10- brake pedal goes to the floor- just changed master cylinder, brake booster, and bled brake lines- did not help


Ok the BRAKE BOOSTER is ONLY there to give you pwer assisted, otherwise NO POWER BRAKES. ( not anything to do with the low brake pedal ) Hopefully the junkyard master cylinder was in better shape than your original. AS far a bleedinda system, heres what I do. First with a1998 vehicle, I would go to ALL 4 wheels , OPEN & CLOSE slightly each bleeder to insure none of them are FROZEN, and they do freeze shut ENSUE THE MASTER CYLINDER IS FULL and CLOSED Now with an assistant sitting in the drivers seat, ready to pump the brakes, and ABLE TO HEAR YOU. Go to the furthest wheel from the master which would be the R/R. DONT touch anything yet. Tell the asst too slowly pump the brake pedal till it gets hard, and then HOLD THE PEDAL DOWN ( and dont let up on it until the pedal drops. If the ast lets up before the bleeder is closed you **** in air.Repeat at each wheel til the pedal stays hard. Hope this helps

1994 ford explorer will not stop, I have replaced the brake pads,


My vote would be the Master Cylinder.
I had a truck sit for 4 years. After getting running again, it did the same thing you're describing. No brakes. I ended up replacing the Master Cylinder to fix the problem. Just make sure you bleed the system real good.
