SUPER LAUBO

hey everyone,

i just did a GSR brake swap to my EK... i used the same EK proportioning valve, and the GSR ABS brake booster + master cyclinder. i reflared one of the lines so it can fit the master cyclinder. when i tried to bleed the lines, i kept on getting a mushy feeling. if i'm braking, the car begins to stop only when the pedal is at the lowest point.

what could be the problem and what are some points I can check???

thanks!!!! :thumbup:

are you getting air in where you flared the line? put some brake fluid on the line and look for bubbles


i'd buy a bench bleeding kit and bleed at master cylinder and then at the wheels also.

i'll check it out..thanks!!

what if it is where i flared the line? what do i do then cause i already placed teflon all over the line. :thumbup:

i'd reflare if that happens. if you are getting air from there you should be able to see bubbles cause well air's going in

get a bench bleeding kit from some auto store its' worth it

okay, i just checked it all out and the lines are not leaking. if i repeatedly press on the brakes, the pedal will feel very stiff... however, once i let the pedal go for awhile and press down on it again the pedal feels soft again.

everytime i press on the pedal, i can hear a swooshing noise from the brake booster.. is that a faulty seal or just a faulty brake booster..

thanks!!!! :thumbup:

it might be a faulty brake booster or MC. did you get it used or new? also check for leaks if you changed out the prop valve. i used the white powder spray to check for any leaks.

it's used.. i did actually see a few droplets of fluid seeping out from where the master cylinder attaches to the brake booster. the prop. valve is still the same factory EK valve.. :thumbup:
