i just got a quote from ford parts , i asked for a new brake servo and master cylinder , i was quoted 83 quid for the servo and another 93 for the master cylinder, am i going mad or are they REALLY that much , i thought they was a LOT less , or should i just go ahead and get the master cylinder, as i think thats whats busted on mine ?

anyone ???

 

I paid Ł100 for a servo 3 years ago and Ł38 for a master cylinder at the same time....

Servos are common for leaking and drawing in air, which in turn effects the running of the car....

 

ok thanks guy , always god to get a fast answer

 

Are the servo's servicable?

 

Daz, any way of knowing if the servo or the master cylinder / resi is the problem for drawing of air?

I think either my servo or master cylinder may have a slight air leak as you mention as when we bled the brakes up a while back you could here "air" when the pedal was being depressed..... not sure if this is normal or not though....but maybe it would explain my slight pedal travel....

 

Does the car run rough?

Get a large can of WD40 or carb cleaner and spray it round all the joints on the servo with the engine running. If the tone in the engine picks up and it runs better then the joint you're spraying is leaking. Also works on any part of the induction system.

Master cylinders do not cause air leaks. If there is an air leak round the master cylinder then it's servo related. Pedal travel is a hydraulic problem within the brake circuits.

 

No, well on the odd occasion it will run a bit lumpy on start up, however I dont think that would be the problem.

Thanks mate, will have to try that

When you say brake circuits, what you mean exactly? Do you mean abs related? I had the abs removed the other week too.
