lose the booster!

[Steer^Gimic]

as far as i understand, the point of having a brake booster is purely for pedal feel?
correct?

if that was to go, and just mount the resovoir to the firewall, which i have seen a few times, will i just get a rock hard pedal feel? i couldnt imagine that would be such a bad thing on the circuit

enlighten me!

IMO a brake system designed for boosted operation is very dangerous without the booster. The required pedal pressure is much too high. The system needs to be designed from scratch with the correct piston area ratio and pedal lever ratio for unassisted operation.

as complicated as that sounded phatsol i think i still understand. im obviosly not just going to rip it out and see what happens. im interested in the whole setup

[ECU-MAN]

dont recomend this but

have you ever driven a car on a tow rope,
if your engine is not runnig you will have both feet on yor brake pedal pushing it though the floor so make it pull up.

the booster is there to multiply your pedal effort to the master cylinder.

i would have to agree with ecu man.

if ur car doesnt have a booster u would b struggling to pull up the car even when going like 10 km/hr

[Steer^Gimic]

ok thanks for the input peeps

[[[d a n n y]]]

with out a booster you have a chance of lockign the brakes even on slight peddaling??

am i right??? people??

No, without the booster you would have to have legs like mr universe to lock up the brakes :p

so...what can one do to lose the booster? if its possible ill do it, if not its going to stay

[crxzzR]

i think if u were to remove the booster, u would need a fairly larger diameter piston, and even then the effort required to stop the car is ridiculous..
like everyone's been saying, the brake booster simply multiplies the effort required by the driver to actually stop the car.
i'd also agree with phatsol on the fact that if this were to be done, everythin would have to be made from scratch taking into account factors such as:
-force required to stop the vehicle
-piston diameter
-weight of vehicle
-desired stopping distance
and the list goes on..
from what i am thinkin.. it doesnt seem feasible to redesign a safety feature which has been highly tested and scrutinised..

[Steer^Gimic]

ok. you all have valid points. as i said, iv seen this done before and just seeing if it was worthy doing.

[crxzzR]

that's cool..
what car was this done on before.. and why?

Did the car have individual resevior setups ( in the drivers side footwell...)
OR just maybe you could of mistaken the lack of clutch resevior (cable tranny)on a car as the "lack of brake master" ?

a crx circuit car, along with alot of mk1 escorts.

and why?
well i wouldnt have started this forum if i knew why, would i??

i wasnt mistaken. its a common site. the resovoir tanks where still mounted in the firewall replacing the booster position.

we ask not to prove you wrong but for more info :) Sounds interesting -

have a read. mixed arguments. both valid
