Check the rear wheel cylinders? Was anything leaking at the master cylinder? Does it have ABS?
Check the front caliper slides are free. Check the front caliper pistons for leaks as well. This is all assuming you bled the brakes(all 4 wheels) properly after all that replacement! You're getting air from somewhere for sure or if it has ABS, the pump may have a problem.
sounds like a broken brake line or a brake master cylinder problem. the master cylinder has a resevoir ontop were you add brake fluid. Does your brake pedal feel spongy? if so sounds like your master cylinder needs to be replaced.
find a good straight away and hammer the brakes. if brakes feel solid. check you brake fluid level at brake master cylinder engine bay, drivers side firewall. if fluid level is ok unplug the level sender at master cylinder resevoir-if this resets the light it is the switch in the master cylinder. If not unplug the switch attached to the e-brake lever.
if the brake feel spongy or fluid is low check for a leak in the hydraulic system.
Check the vacuum booster first Shut the car off after it idles for 3 minutes Apply your foot on the brake and hold If the pedal seems hard at first and did not go down all the way keep your foot on it for two more minutes If the pedal gradually goes down to the floor the brake booster is leaking If not start the car and let idle again \With the car still idling step on the brake pedal again and hold If the pedal goes to the floor in a second the master is shot instead
check master cylinder but after brakes are bled with vehicle running brake pedal pushed down should be even with gas pedal you have to allow extra movement due to vacuum assist you only have this when vehicle is running pedal is only hard when engine is off
Does sound like you need a new master cylinder. On a 2000 you wont need to back bleed. You will just need to follow the instruction and bleed the master and all four points. you will probably need to bleed the ABS block and proportioning valve but only if they have bleeders on them.
Since your brake fluid level has not gone down, leaking calipers or hoses, letting air into the system can be eliminated.
Suggest you run engine, and sit with your foot on the brake pedal quite hard, and see if it drops drastically.
If so, this points conclusively to the brake master cylinder, and being a 2001 model, is a distinct possibility.
By the way, as you have dual system braking, you should never loose your brakes completely, nor the pedal reach fully to the floor.
The other possibility is excessive play, in one of your front hub wheel bearings, allowing the brake pads to be pushed back on cornering, then on first application of the brakes, you will have to pump the pedal.
Hope I have been of some help.
Good Luck !
Please don´t forget to give me a FixYa rating thanks !
have the brakes bleed first and if that does not take care of the problem have the master cylinder checked because the check valve in the master cylinder could be bad
