How bleed the brakes with ABS?

[Tom_]

I changed brake lines and hoses,than put new brake fluid and bleed the brakes.Yesterday during test drive,when i brake the brake pedal is going too low and sometimes i heard a ABS . Its any differences to bleed the brakes with and without ABS?The car is cq20v.

Thank you

you should start at the wheel the furthest away from the ABS. Then other rear side, front furthest, and then nearest.

And best to go round 2-3 times to make sure.

[Tom_]

i do that,but its no good...

[Henkjan]

how did you bleed? did you use a pressure source such as the ezbleed, or the old way using your foot on the pedal?

i am using a foot on the pedal....

[stocious]

just a thought , did you have your master cylinder removed whilst you were doing all the work ? and if so did you bleed it on a bench before fitting to the car.

[Tom_]

No master cylinder was fitted all the time.I only get out the brake fluid contanier to flush the rest of the fluid,what was there

Then you need two people or one-way valves.

yes,i did it with my mate

push the peddle, open the nipple, push peddle to floor slowly, do nipple up, pump peddle 10 times, then repeat the process.

Repeat the process each time remembering to pump the peddle 10 times gently between each go. i have never found this to fail me or my brother who is a mechanic.

Strongly suggest that "push peddle to floor" is TOO FAR. By doing so, you will push the piston and the seal past their normal area of action, past what might be a "lip" in the cylinder, potentionally damaging the seal, necessitating a rebuild or replacement. Better to limit travel by placing some block of wood on the foot board behind the peddle.

[Christophski]

Or do the above I have never done that but maybe I should

That's a really good idea, I'm going to do that from now on.

OP, I'd try pressure bleeding the system in the same order.

Never had a problem bleeding the an ezibleed pressure bleeding system. HTH

And don't forget the clutch slave which uses the same fluid as the brakes. Do this last.
