V8 finally started after 3 years of sitting, over the moon
brakes
how did they test the front brake balance?
Must have super clever kit or did they note this on a test drive?

they have a 4x4 rolling road. i believe they put the brakes on then turn the rollers.
the resistance is then measured - if a brake is not working correctly it will not take much force to spin the roller. they then measure the resistance between each wheel.
how do you judge how good your vacume is? when the pipe is removed and placed against skin it pull hard. air flow meter?
l have never opened up the servo - has anybody overhauled one? any pics or advice would be much appreciated.
the tester said that the white plastic 90deg bend unit that the pipe pushes onto at the servo can fail before the diaphram.

Struggling to remove servo tonight. Cannot drive out pin that holds servo rod to pedal mechanism as Top of wing is in the way.
Master cylinder is off the two bolts at the front, 4 bolts holding servo at back removed.
Am l missing anything? Or easier way of removing servo.
Darkness didn't help either.
Only the hand brake and this servo to sort now

Why don't you remove the servo complete with the pedal assey. It'll be much easier to strip on the bench ![Smile :)](./images/smilies/icon_smile.gif)
Out of interest are you servicing the servo or replacing it.
I think this is the correct kit for it

Good luck...

right then, the servo is out - did not realise that the 6 holding down nuts were welded to the pedal box assembly allowing for easy removal - doh!
pulled the whole lot out and fitted a spare servo and pedal box - unfortunately that too was nackered so l am still without a working servo.
currently found a new brake servo assy -STC1816 for £65.99
Has anybody fitted an overhaul kit? Part No. 18G8951L £23.15
if so how easy was it to fit and was it successful?
has anybody also removed the one way valve? 18G8953L does it just pull out?
thanks

The overhaul kit should be really easy to fit. The only critical bit (assuming the non serviceable diaphragm is ok) is the seal between the master cylinder and the servo together with the vacuum pipe seal and valve (yes, it should pull out). The seals and filter on the pedal side of the servo shouldn’t affect the operation of the servo even if totally shot or missing, although not ideal of course.
Out of interest was there any liquid in the old servo. I’ve found servos in the past to be full of brake fluid because of previous failed master cylinders. A common problem as the servo would normally remain in situ and most people would not think to check to see where the brake fluid has gone
In extreme cases you’ll get white smoke coming out of the exhaust where the engine is drawing the fluid out and burning it.
As for what to do – I would try the Lucas repair kit (not the other brand!!!) and see what happens. A genuine new servo is prohibitive so the question is would you trust the “other brand” at a mere £65![Question :?:](./images/smilies/icon_question.gif)

Thank you for the advice -
l havent opened the servo up yet - looks like a fiddely job to prize it off.
the end of the shaft that goes into the master cylinder, the rubber has perrished and cracked slightly - could be the cause.
l was very cautious about removing the one way valve - the plastic and rubber seal were getting chewed up so l have left it in place. there was a good seal between the pipe and the valve.
original servo l found for £225!!!
no thank you. repair kit it may be!

I do hope that you DO NOT intend on splitting the servo
This is not to be done at any cost. The overhaul process is done only at each end; the master cylinder end and the pedal assey end.
If you damage the valve and seal then order a replacement. Don't pry it off just pull it straight off.
