My Warwick has its brake sevo disconected. The previous owner said that it braked better with out the sevo and in period owners did the same!. The car stops ok. But I have not had too much time to drive it lots of miles. Any opinions on should I connect it up or leave it alone.
I would suggest trying it (not on a public road) and if there an improvement then a rebuild before relying on a critical component of unknow origin.
In my experience if you use it and it works you then rely on it and then it fails.
i cooked my front pads on track days. I have fitted new pads and the improvment was so marked I have not bothered with a servo, but I do have one in stock!
