Brake Master Upgrade?

[bubbabooga]

hey all..

recentlly put r33gtst front rotors (redrilled to 4 stud) and calipers onto my a31 cef.

still get standard back brakes.

now the pedal feels a bit spongy compared to full standard setup.

my question is will r33gtst brake master and booster cyclinder rectifiy this spongy pedal problem??

the lines need to be modified slightly to work with this master yeah??

searched but couldnt find exact answer to my dilema.

cheers lads

Spongy pedal is usually air in the system (poorly bled).

[bubbabooga]

their their bled properlly and work fine.. just slightlly softer pedal feel which id like to rectifiy.

[scandyflick]

what bmc do you have fitted at the moment? itll say it on the side.

[bubbabooga]

just had a suss it says

bm58?

[bubbabooga]

any idea's fella's?

More likely it's BM38 - standard 7/8" BMC. R33 gtst uses BM44, which has 15/16" bore. Changing BMC is unlikely to fix spongy pedal, as it is usually something else that causes that spongy feeling, but it will reduce pedal travel and increase force required to be applied by your foot. If that is what you're after, then by all means do it.

[bubbabooga]

ahhh sweet sounds like what im after.

do you know if their is any modification needed to the lines? or straight bolt up?

cheers

Nah, sorry man, IDK for sure, but I _think_ it may be bolt on, as AFAIK A31 chassis is pretty close to R32, so line routing should be similar. 

If you post a pic of your BMC I'm sure people here can say if it's bolt on or not by the looks of it. 

Make sure you get yourself correct BMC though, i.e. the one suitable for ABS if you have anti-locking brakes (with two outlets), and non-ABS otherwise.

[bubbabooga]

ah yep my setup is non abs. il just wing it. not to hard re routing a couple lines if worst comes to worse..

bm44 it it

cheers for the help lads
