Has anyone ever looked into how to reduce the brake servo assistance on modern cars?

 

I only have to touch the brake pedal on my Ford and it seems waaay too sensitive and over brakes wildy unless I keep it in mind. Maybe installing some sort of adjustable bleed valve off the main vacuum pipe to the servo would work well. On my car I think vacuum is provided by a mechanical pump.

 

Any ideas?

I wouldn’t know how best to tackle your dilemma but just want to say I feel your pain. I too hate the fact that in 99% of modern non driver focused cars you only have to sneeze on the brake pedal in order to involuntarily head butt the windscreen. I guess manufacturers feel they have to cater to the lowest common denominator ie. Arthritic ankled OAP’s with the reaction times of a dead sloth. Personally I find such cars tiresome to drive when you have to be so delicate with all your inputs and are so devoid of any feel.

There are brake boosters you can get on non servo'd old cars.. one would assume they are adjustable..

Could you try limiting the amount of vacuum the booster sees? Some form of restrictor spliced into the servo hose line? Not sure if this would work.

Yea, an adjustable bleed valve, I have one somewhere, might try installing it if I actually have any energy after a day at work.

You might want to have a think about the insurance implications of the proposed mod?
