ABS accumulator - any luck with the Wabco unit?

Recommended Posts

Hello

having mostly sorted my ABS brakes the last problem was a slow leak at the threaded join on the accumulator bulb. 

I had purchased a £90 unit that was for a land rover I read would work....and although it screws in ok the threaded neck bit is different and I wonder if that is why there is a slow leak?

Thinking I would kick for touch I ordered the unit from SJ ( at £300 including postage 😳) and I was disappointed to find the same wabco unit turned up - damn. 

Anyway can't do much about my stupidity- should have asked before purchase.

Has anyone got these to work with out leakage?

The rover one had an o-ring the "lotus" one does not have one - should I use an o-ring or not?

thanks for any help

Iirc - you are supposed to fit another washer there - as it’s not an original unit and it’s slightly different

What I did was ordered the WABCO unit and had them turn down (machine) the neck to match the Lotus unit.

I have sorted it - have used a thicker o ring than the purple one supplied.   Wish I had tried this first!   Anyway I have a brand new accumulator for sale if anyone needs one - comes with upgraded o ring!!!

Hi Alastair, where did you buy the ring from, is it specialised rubber or metal, did you modify the WABCO shoulder in any way and for how long has it not leaked? I have one ready to fit.

Hi Alastair, without machining the shoulder could you tell how many threads hold it on?
