Default Replacement brake accumulator

I couldn't find the original part for my 1994 XJS 4.0, at a reasonable price, so thought I would look at alternatives. Ordered a Bosch unit as fitted to AMG Mercs and Maybachs. It is a little smaller but screwed straight in. Took 32 seconds to charge initially and takes 23 brake pumps to empty it so I think it will work just fine. $85 Ebay.

Does your 95 have ABS?

kansanbrit,

Thanks for the info. It's always useful to know of alternative parts.

carsnplanes,

The brake system changed to a traditional servo type at VIN 198335, around November 1994.

Cheers

Paul

Still working fine. Amazingly no bleeding was necessary.

Hi Kansanbrit

What sort of Tool did you use to unscrew the Accumulator, as I am going to put a new one on my Car 'Cherry Blossom'
How much of a problem was it to unscrew?

I used an allen key socket with ratchet and held the assembly from twisting by using a G clamp. Once it's held solid it just needs a bit of force to break it loose.

Hi Kansanbrit

Many Thanks

I did my Car Today but getting the Ball unscrewed was a bit of a Nightmare!
