hi all, i need your adivse on this one...

basically i bought the GSR MC and BB... i have already benchy bleed it then bleed it agian on all four wheels.... the pedal was firm, but wen i start up the car.... the pedal is realli soft... i turn off the car n pump the pedal a couple of times and it firm up again...

do u think i still hav air in the system? do i keep on bleeding? is the MC or BB faulty?

any help would be apprrciated,

thx in advance

 

I would like to know also.
But I'm pretty sure the answers are out there, but just gotta search.

 

when you turn off the car the pedal firms up because your using up the vacum thats left in the brake booster. if when the car is runing it still feels spongy than you still need to bleed it some more.

 

how do u bleed the brakes? in what order? coz that might be where the problem is.....sometimes.

i hope its not a faulty mc or bb

 

bleed from passanger rear to drivers front.

 

if its just a soft pedal then air is probably the problem, if it slowly goes all the way to the floor then i would blame the MC.

 

bleeded the brake a couple of times now.... there was still air in the system.... going to take it for a qucik drive... thne probably bleed the brakes again....

its gettin better... thx for the help

 

guys, brakes are still spongy.... its abit better than before.... hmm... bleeded them 4 times already....

do i keep going until they are firm??

or am i doing something wrong??

 

are they spongey all the time or just everynow and then, a faulty or bypassing master cylinder will sometimes give you a great pedal and then all of a sudden it will suck, might be time for a nother one

 

You have to bleed with the car on, hope your doing that. Then you have to have a hose in a bottle of brack fluid, hope your doing that. Then bleed rear passanger, rear driver, front pass., front driver. When doing so have someone pump 7 times then hold on the 7 then you loosen the bleeder valve.
