Check the vacum lines going to the brake booster. if everything is connected properly you may need a new booster.

Renault megan. Intermittent loss of brakes, then pedal goes hard

Make sure the emergency brakes are back off and adjusted after pad replacement. A lot of mechanics forget or don't know about this. Also check the master cylinder. Push on brake pedal hard and see if it sinks to the floor, if it does then the master cylinder is bad. If there is air in the brake system it is best to pressure bleed or vacuum bleed the brakes to get the air out. Often when using the two person pump the pedal and hold will not be effective in getting all the air out if a line is broken and then replaced.

No clutch pedal after fitting new clutch pugeout 407

you have an air bubble in the system.. keep bleeding it and it should return. if the clutch master cylinder is like a ford then you actually have to remove it to get the air out by holding the master at the right angel for the air to be completely removed....

I am working on a 2004 dodge caravan with a soft brake problem.i have replaced the rear shoes and adjusted rear brakes,also replaced front rotors and pads.i have also replaced the master cylinder.after...

try bleeding the master cylinder at the lines first as it indicates that there is still air in the pistons
loosen one line at a time and gently apply the brakes until any air bubbles come out tighten the line before releasing the brake pedal
do it for the other line and then bleed all the brakes starting at the longest line first and ending at the shortest line

Can anyone tell me how to bleed a master cylinder for a 2001 isuzu rodeo with abs? can i bleed the master cylinder with it being attached to the power assist, or do i have to bench bleed it?

You definitely have to bench bleed the master cylinder, and once you have replaced it in the vehicle, you will need to bleed the brakes from the calipers to remove any additional air.
