164 Mk1 rear brake compensator valve

Well, it looks like mine is leaking! I had hoped it was a dodgy connection on the reservoir float, but no, I really was losing brake fluid...

So I think I need to find a new one...

Would anyone have a source they could recommend? 9Or a part number I could search for) please? So far, I've found out that (I think) Alfa call it a "Brake power regulator".

I have a Bosch part number of: 0 204 131 202

A TRW part No. of: GPV1057

Fiat part numbers of: 82407503 or 60801503

2. OEM Numbers:*42562769 / 60801543 / 82407503 / 98420511.

Does anyone know which (if any!) of those is right for my car, please? (It's a Right Hand Drive 3.0 V6 Lusso of 1989 vintage).

Hi Avocet,

https://www.autodoc.co.uk/bosch/674964, listing in stock at £83.28 + £8.45 delivery for bosch 0 204 131 202, but its listed only for the 155 (Its no good asking them, they employ idiots). double check your existing part is bosch 0 204 131 202 and compare the pictures.

Other sites are listing that bosch number for the 164 but autodoc is cheaper by a long way
hope that helps ;0)

Thanks DaisyGTV,

Sadly, no that one looks different to mine. I wouldn't be surprised if the internals were the same, but the actuating lever is completely different to mine.

Does your car have ABS? If so, you can likely just bypass that valve. Worst case, fit a simple limiting valve.

Be interesting to strip one out and see just what is under the rubber boot, can not see it being anything more than the linkage as the same part number is listed for several different makes an bosch certainly wont make them with any real difference.

This looks identical to the bosch one https://www.autodoc.co.uk/abs/7716088 and is also listed for the 155, but its only £28 ?.

Yeah, I've always wondered that! Why does a car with ABS need a compensator valve? Surely if the ABS is any good, that'll stop the rear wheels locking!

I think the answer is that whilst it has ABS, it doesn't have Electronic Brake Force Distribution. It would therefore allow wheel lock to occur (even though the ABS system would then unlock it again). I therefore think it's there to limit the rear brakes to the point where lockup would be extremely rare, so that the ABS would only intervene on the back wheels in very rare circumstances?

I found one which (at least according to the photo and listing) is right for my car, for £116 delivered, so I'm going to try with that, I think.
