unstopable tx3

[GAW]

good mornibg all . i have a ka laser tx3 that ive bought for my daughter ,the car runs and goes great however the brakes seam to faid occasionaly .have bled them and replaced pads but no improvment ,the car has plenty of brake at one minute but at the next intersection the peddle goes allmost to the floor before it starts to pull up . ???????

fix or replace the master cylinder

before the brakes fail

check the booster for a vaccume leak but
my guess the master is bypassing the cups internally

Just letting you know mate there were no KA Laser TX3s.. The two door KA Laser's were the Laser S.

i have the same problem in my av tx5. it works fine 4 a while then amm of a sudden it feels like i have no brakes. my mechanic said the master cylender is fine so im just gonna put up with it 4 now. (there is always the hand break if things get bad)
