Peddle really hard

[starletgt-shady]

Hey guys my brake peddle is rock solid

I took the vacuum off from the inlet manifold to the brake servo ( I think, big black round thing) to change it to suit uprated manifold. Air came out under pressure when I took it of. Is this my problem with the brakes?

Any help be great thanks.

Yep certainly will be unless you put it back on the manifold? I'm sure aftermarket inlets have a fitting for the servo?

[starletgt-shady]

Yeh it all back together. Took the fitting of the standard inlet and put it on the new one. Only disconnected it to put a longer hose on.

Does the system need to be bleed again?

You shouldn't need to if all you did was take the servo/vaccum hose off then replace it. :-)

[starletgt-shady]

Yeh just took it of and replaced it. I am using wms 4 pots. When I took the vacuum line off pressure came out.

[Keri-WMS]

Same thing happens if you pump the pedal a load with the engine off - the pedal goes hard as the vaccum is lost. Start the engine and it puts the vaccum assist back, and the pedal goes soft again!

[starletgt-shady]

Yeh that's what I thought. When it's running it doesn't get any softer. Can you bleed the servo?

[Keri-WMS]

There's nothing to bleed in a servo itself. Have you got the hose back on it? Also most servo vaccume hoses have a one way valve in them that you'll need (if the OEM one had it).

[starletgt-shady]

Yes the hose is back on with the one way valve on. I'm pretty sure I put it on the same way I took it of but could put the valve in the other way see if that helps.
