Brake servo air leak

Hi,

I have an air leak between the brake master cylinder and brake servo unit, which causes loss of vacume under heavy breaking, is there ment to be a rubber seal between the two units? Has anyone else had this problem? Both the master cylinder and servo unit are a year or two old and are britpart. Had no problems so far.

Thanks, Rich.

yes,but wouldnt come with either

There is a seal but thats to stop water ingress, it would work fine without it.

There is no air between the servo and the master, the vac pump is connected via a hose to the servo, the vacuum stays in the servo, it doesn't in anyway go to the master, only an assisted actuator rod comes from the servo and pushes the master in.

If there is an air leak letting air into the servo system then check the hose, the connections, and the servo.

Hi.Check out my post re EGR mods if you've done the EGR thing

the joint should be sealed otherwise youd have no vacuum

Where? Between his servo and master? I don't think so. Look at a diagram of it.

^^^^ Agreed. I've just had mine apart.

Thank you.

I thought I was going to have to get the spare servo out my cupboard and start taking photos for some people.
