the car = 95 accord lx 4 door with abs. FRONT & REAR DISC

the problem = as I press the break pedal, it tends to go to the floor & just slow down the car, but not really. If I pump the break pedal 2 times it works fine.

The reservoir under the hood is full.

What can be the problem ???

What should I look for ???

Brake fluid dirty maybe? If so, try flushing it. When did you last change the brake pads?

 

Air in the lines? When was the last time you bled them?

 

bought the car in 04 & havnt changed the breaks

 

master cylinder is done...buy a new one its like $80 plus core at any autoparts.

 

How can i check to be sure that that is the problem ???

 

Your drum is out of round. Change it asap!!

 

the only time to change the master cylinder is when you see blackish fluid which cause by defected rubber seal.

 

you need a brake master cylinder , no out of round drums if the pedal sinks to floor while you brake you have an internal leak in brake master the inner seals are worn and cannot hold pressure replace it asap

 

master cyl test, at a stop pump the pedal and hold it, if it begins to fall you either have leak or the master is bad. but i believe your rear brakes are not adjusted correctly, to check set your parking brake and then step on the brake pedal if it feels firmmer and higher without pumping that is your problem.

 

master cylinder......had the same problem one time......

lol

back to the topic... its most likely your primary or secondary cups in your master cylinder. take sinister2c's advice and buy a new master cylinder.

 

Master cylinder....easy to replace but make sure to bleed your brakes after installing the new one .

 

How do i test it to be 100% so I dont blow $100 relpacing it ???

 

If you pedal goes all the way to the ground and you have already bled the brake system then it is without a doubt your MC.

NTM if you replace it and it still does it just take the part back .

 

Would it be possable that my break pads need changed ?

 

read all the posts.... master test

it is possible you have a caliper problem that is compensated for when you pump the brake pedal a couple of times

take the wheels off and inspect everything, look up under the dash where the master cylinder push rod hooks to the brake pedal, is ther brake fluid around the gommet?

They are special wrenches that won't strip your brake lines that run into your MC.
