hey guy's

just bought a new car, 2001 bug wrx

it has d2/k sport 8 pots on front, with good discs and pads, and the oe one pots on back, again plenty of life.

problem is the pedal is near on the floor for any braking.

we have replaced all the fluid today and bled correctly, ive adjusted free play but the pedal is still terrible.

ive checked the one way valve to the manifold and thats fine, im thinking servo?

any ideas

cheers jake

 

Have you tested the brake servo?

 

Forget the servo if you can't get a solid pedal with the engine not running its something else. If your positive you've bled it correctly I'd be looking at the master cylinder. Or possibly a wheel bearing.

 

Not tested the servo,

I get sold pedal without the engine running, as soon as it starts the pedal goes soft. How do i test the servo?

 

If you have a solid pedal at the top of the travel and you then hold your foot hard on the pedal it should drop when you start the engine. If it does and the pedal goes to the floor I would suspect that it needs bleeding again That has near enough tested the servo. When you stop the engine you should get 2 or 3 possibly 4 pumps on the peddle before it goes rock hard again.

 

Thats what im experiencing, ill give it another go at bleeding, just cant understand why it wont bleed up thats all,

Not sure if it matters but were bleeding the inside nipple first on the fronts

 

Bleed nipples are at the top of the caliper ?

 

They are,

The brakes have been fitted for over 2yrs

 

sorted, both inside pads were siezed into the sliders due to corrosion, so the pads wouldnt move.

ended up with a set of new pads, a full strip down and clean and refit,

nightmare, but now i have brakes
