abs pump

[sharki786]

Ye i have (yellow stuff front and rear pads with all round grooved discs and mk4 rear calipers with braided hoses) i pushed the pistons all the way back with a rewind tool for the rear. My cousine bled the brakes last time with the eezi bleeder kit and they were solid as feck (excellent bite) but the rear calipers from the mk4 were leaking so i changed them the other day with mk4 calipers again and this time i bled them with the 2 man bleed (1 pumping brake pedal, other openeing the nipple) going to my cousines garage today to bleed with the eezi bleed and see what happens. Will keep you guys updated.

So the pedal dosent go all the way down is it firm but still spongy

[sharki786]

It does go all the way down but it does have some resistance (gets harder towards the bottom)

hmmm it shoulnt be going all the way down if u let it settle then hold the pedal if it goes all the way u got a prob somewere have u checked the bleed nippples for leakage try bleed the master cylinder have your pads bedded in tht can make a crappy pedal if there fairly new other than that only other things i can think.of mk4 calipers are crap for bleeding i changed pads all round on a vw beetle same calipers as a mk4 and the pedal was going all the way down even though i had to bleed all the wheels still no better if nothing works then just drive it like that and hopefully it will sort itself out the mistake i made is u do 1 side then pump the pedal and then do the other side i have only experianced these problems on a mk4 braking setup

did the fluid level drop below the minimum when you were chaging the calipers? if so check to see if there is bleednipple on the master cylinder there usally is but is a right pain to get to, you could have a slight airlock in the master cylinder and no amount of pedal pumping will get it out

Thanks for the advice and all the help inc a MR DH
My cuz bled the abs unit and they are working better. All he did was tell me to hold the brake pedal down and undid the pipe nut then tighten them up.l. Done them 4 times each one and 1 had some air in it.

Bled my system today, drained the old fluid through normal procedure at each corner, bled the MS, ran the pump, bled it again and got rid of some more air, got lazy and and used gravel drive to run abs pump, did all four corners again, perfect pedal

How did you bleed the ms and ran the pump?
