Better brake feel

I read too that larger master cylinder will make it harder to press/less sensitive

But, also with a smaller one the travel will be too high?


What about all those firewall flex stoppers, do they do anything??

That's the cylinder brace or brake cylinder stopper. Improves braking feel.

^got pics??

imo stopper doenst effectively change the performance of the brakes.

try some stainless steel braided lines, improve pedal AND responce :thumbsup:

id go larger booster,teflon coated braided lines,new brake fluid,master cylinder stopper, and a good brake bleed to try and get as much air out as possible.. i.e manual bleed.

also u could upgrade caliper to a multiple pistion instead of single piston

then also get better brake pads... ?

^ that would change the brake feel and performance drastically for sure hehe

The fronts are twin pistons calipers
And I am thinking of upgrading to 294mm DBA 4000 rotors (mine are 276mm now)
Along with the rest of the stuff, and maybe use wilwood 4 pot calipers too depending on price etc

how old are the calipers? the master cylinder? when was the last time the brakes were bled properly?

brake feel is a combination of a number of factors, and it is difficult to say "it is ABC causing your poor pedal".

I've posted before in another brake thread, but to get the most from your system you should:
- make sure the brake lines are not blistered or brittle / old. Braided are not strictly necessary on the street, but will help firm up feel a little. You will find the difference between a brand new rubber line and an old rubber line like night and day.
- make sure the fluid is bled correctly, and use a quality DOT5.1 or like brake fluid. note it may also be worth flushing the ABS system too; it is sometimes overlooked (not sure if all brake systems bleed the ABS when you bleed calipers, my older system on the GTR has a separate bleed on the ABS block)
- the seals on the master may be rooted; does it require a resleeve?
- seals on the calipers could use a rebuild; do they leak/do they move in and out of the caliper smoothly? surprisingly a couple of year old caliper seal can well be rooted from heat cycling
- brake master cylinder brace; some firewalls flex in the order of 1cm or more during braking... doughy brake pedal anyone?
- what is the pad compound? a harder track based pad will feel crap until it warms up
- does the rotor face / brake pad face have scores over it? if the rotor is grooved a machine may be in order, just get the pads faced...

if all these things are in order, i would expect your pedal 'feel' to come good

if u cant fabricate a brake stopper yourself then you really should save that 150 of yours and do something else..

Although it gives you a firmer pedal feeel. you stopping distance will not improve.. its like getting and exzorst for sound and not performance..

hello guys
i know its off topic but where can i buy a quality steel braided brake lines & a contact # will b gr8, ta!

Maltech do ADR compliant braided hoses to suit your car.

Firmer brake feel is a personal preference IMO.
True it doesn't improve braking distance but a better feel can result in more confident braking. It also may change brake pedal travel. Which can also improve your driving in terms of heel and toe. Having to really stand on your brakes while blipping the throttle can be difficult and akward for some.

Some people just like very touchy brakes that bite progressively till the point of lock up. Kinda gives you a higher sense of control. Jumping on your brakes, only to have the pedal go into the floor isn't fun.

A brake brace would be your best(cheap + easy) bet for this result.
