Hi all,
Like many others I had an ABS unit that was leaking and did not want to put another 15+ year old unit on that wasn't leaking yet but was going to, probably 2 minuts after I had paid $400 for it.
Having looked around here on the forums it seemed no one had ever tried to repair one. Since I have a background in brake cylinder resleeving, I had been given many odd things to rebuild and repair because they were either too old or expensive to buy new.
I decided to try to repair mine. What was I going to lose? - I already needed a new one !!!
Anyway, I pulled the thing apart right down to nothing to find the internals all in good condition mainly because they are all made from aluminum and therefore doesn't rust or pit easily. Just the seals had gone hard.
So I tracked down a company that sells EPDM seals (the only material that holds up to brake fluid) and we went about matching them all up (about 36 of them). We found all except one and I started the reassembly.
All went well. Four hours went past and I was refitting the unit to my car, bled the system through and hey presto - Job's a goodin.
The unit has now been back on the car for a few days and all seems to good. Brakes work as new and abs funtion is perfect with no leaks .
Any-one that has some mechanical knowledge and the right tools should be able to do this without too much hassle.
I will keep this updated if any problems arise or if any one wants some help doing there own.
GIVE IT A GO! WHAT DO YOU HAVE TO LOSE? MY UNIT IS NOW AS NEW, NOT SECOND HAND.
