Folks,

Im looking at removing my brake servo and was looking to see if anyone has done this before and has a 'how to' guide? or any help in the right direction would be appreciated!

First question: Why do you want to do it (ALS?)? If you're not already aware, you will end up with a very hard pedal. You'll probably get used to it (and pad choice helps) but it can be disconcerting at first, and isn't ideal on a standard master cylinder.

The how to isn't that difficult. Take the servo off, punch out the guts and get a solid rod made to length to replace it. Put the gutted servo body back in with the rod going through it, put the cylinder back on and attach the rod to the pedal at the other end, and then find something to bung or block the vacuum takeoff on the inlet manifold.

There's a Group N homologated rod and servo replacement collar which you could fit if you're flush and want something that looks trick. Buying an old servo from eBay and gutting that might not be a bad idea either. At least then if you decide you don't like it, you have everything you need to return it to stock.

Incidentally, is this on an ABS or non-ABS car?

 

Are you sure you want to? Disconnect and block the servo hose and see what the brake pedal weight is like, you may change your mind - or decide you need a smaller master cylinder to cope!

Thanks for the quick replies guys.

Its for my rally car and i have driven cars without servo before. I like the feel through the pedal and it gives you a better idea when the car is breaking of whats happening (to me anyway). At the moment i run mild ALS but to run full ALS the servo has to be removed (as far as im aware).

Its on a non-ABS car!

 

Retrofitting a master cylinder off a car without a servo might be a way forward.

Master cylinder from a MKII VW Polo would be a good candidate.

I understand what you mean about unassisted brakes; with a good setup, the feel and proportion can give the driver superior (real world) feedback.

(Same with binning the power steering and having a manual rack - not suitable for those with girly arms though ).
