some times when i brake my brake pedal get real soft and goes all the way down. Then when i release and press again it goes back to normal what could be the problem?

 

air in your brake lines

 

Or master cylinder's bad...that's what's letting in the air

 

Don't take this problem lightly. Your brakes are VERY important and you should get this solved ASAP.

Start by bleeding the brakes until the pedal pressure is firm. Take it for a little drive. If the pedal still goes down, you may have a leaky MC.

 

ok thanks. But would that make the car pull left or right?

this is another problem. wraped rotor. or un-even wear of pad.

btw: master cylinder is for clutch, booster(big black circle one. next to master cylinder)is what need to be checked.

Actually, the clutch has its own clutch master cylinder and also a clutch slave cylinder. The clutch master cylinder is next to the brake master cylinder. The brake master cylinder is mounted on the booster. If the brake master cylinder is leaking fluid, it could ruin the booster if enough gets inside. Check the fluid level and look for fluid going down the bottom of the booster and on the fire wall.

If your pulling to one side while braking, it could also be a dragging caliper or one of the two circuits in the master cylinder has failed.

 

REPLACE THE BRAKE MASTER CYLINDER FIRST DUE TO ITS GOING BAD THEN HAVE TO BLEED ALL THE BRAKE CALIPER AFTER.
