no brakes

[Piggy]

this is weird.

You sure the calipers arent seized or blockage in the lines?!

[padge]

changed calipers, and its still the same, going to change the MC and bleed them again, then move onto possible callspsed line/s?

brakes worked 100% on the car it came off, i know the car.

[padge]

tried a working one way valve, no difference.

This is really strange Padge......if you haven't checked already (which I'm sure you probably have) have a look at the braided flexi pipes on the vac line between the vac pump and the servo.

One of mine looked compressed, the one straight after the pump and bulkhead pipes, and when I opened the braid up it had two 30mm splits on opposite sides of the pipe.

[padge]

hmmm, dosent seem to be fluid going to the back cylinders?

[Piggy]

odd...v odd

[padge]

when you press the brake pedal, the fluid drops slightly, in the MC then when you release the pedal it comes back.

[Piggy]

all very weird.

you getting fluid at all four corners when nipples cracked open?

[padge]

none at the back, fronts seem to flow fine

[Piggy]

odd.
so....vacuum pump creates a vacuum?
servo holds the vacuum?
front calipers not seized?
rear compensator free?
master cylinder not leaking?

[padge]

all of the above work, we havent checked compensator

[Rippthrough]

Sounds like master cylinder has a leak on the rear seal.

[padge]

changed MC, and its no different, even changed the seal.

[Piggy]

get fluid to the rears....nothing appears to be wrong apart from that...it may be nothing to do with the main fault but it needs fixing anyway and may point to the bigger issue

[Rippthrough]

Very strange that there's no fluid to the back if the M/C is okay, is the compensator moving freely?

[padge]

not checked that ripp, we are thinking a collapsed rear flexy? strange how 2 can f*ck up though.

[Rippthrough]

Would have to be 2 for both rears to have no fluid though?

[padge]

bypassed the compensator, had some brake pipes made, we have fluid at all 4 corners, but brakes are still crap, the backs lok up and the fronts dont.

[Piggy]

thats what the compensator stops happening!

this is so odd

[padge]

im furious tbh, wish i never bought it

[Rippthrough]

Yeah, they will lock up with no compensator in, especially if there's still air somewhere.

[padge]

well, the fronts dont lock up at all

[Piggy]

hmmmm. is the piping all right?? as in circuits right?

[padge]

Going to change front flexys tommorow, piping looks ok.

[Birk]

Abs unit could be buggered.

[padge]

we unplugged it, it brought the light up, but there was no difference lol, ill try flexys tommorow, then abs pump.

[Birk]

The brake lines go into the abs before going to the calipers, so it wouldn't affect the pedal if you unplugged it if it was partially blocked or damaged.

[Tom]

Think we need a recap on exactly what the problem is. And pedal operation described perfectly. Still weird though because you've changed almost the whole braking system whats left :/

[padge]

only things left to change, are flexys and abs pump,

[padge]

fluid shoots out of the front bleed nipples, and brakes are still shit.
