i know its not a repair kit but if you want to get a bosch brake master you can get them from ferris pistons, motor factors it cost about 65 quid. i stuggled like mad to get one but they do them and its oe bosch..
if there isn't a kit available that is 100% reliable £165 or your life doesn't seem such a huge price! is that motor factors price or main dealer? as Karl has said you can get one for £65 which is decent imo. even if youhave to get it posted to you it's only gonna be £70-75 max
as for spongy i used to have the same problem with the mk2 even with a new master and new calipers that is until i stripped and cleaned the abs module out
no one ever properly flushes the fluid out at all nowadays so it congeals like crazy after a couple of years, bled em over and over ubtil one rear pipe just blocked up solid - new pipe fitted still same ?? stripped and cleaned the abs solenoids all worked dandy .
hi flapper i did the abs bleed proceedure but only produced about half a litre out of each front what could be the problem there, also do these cars have abs on rear as i know the golf mk4s do,stripping the abs unit is it simple to do?
