Default Genuine Brake Accumulator JLM1907

My Brake/ABS warning lamps have been coming on more and more often. Just this last week I've even been getting the red Brake warning lamp illuminating when driving. Not good! Also, its a bit annoying having to "reset" the ABS warning light by cycling the ignition after the accumulator charges up every morning.

I've been searching around and after looking at our trusty Jaguar parts suppliers, eBay, and a few other sites, I've stuck to good old Jaguar Classic Parts. It appears that they have the best price for the OE Jaguar units. I was thinking about going with ACDelco, but wasn't quite sure about their exact performance differences.

Jaguar Classic Parts listed the accumulator as £234.74, but I'm assuming that's including VAT, because the price dropped to £194 ($239) after entering my shipping address. DHL International Shipping is £18.19 ($22), which brings the total to £213.81, or $265. I don't think that's unreasonable for a genuine Jag part.

Most of the AC Delco units now are selling for more than that, ($280-300) and Jaguar OE units are selling for almost twice that ($400-525) from some vendors. With the current conversion rate, this is the time to stock up on these and other parts from Jaguar Classic Parts.

Nick,

Thank you for your report and the helpful information.

I will be very curious to know the markings stamped into the new accumulator you receive which may help us know whether the manufacturer was ATE or another supplier.

Cheers,

Don

I will be sure to let you know! Orders from JCP are lightning fast, usually get here within 2-3 days, so it shouldn’t be a long wait!

Another thing to consider is that NOS (NEW-OLD-STOCK) accumulators do degrade over time. The nitrogen charge can 'seep' and a low pressure unit is as bad as a used one.

Hope they are relatively NEW manufacture.

If I had to get one, I'd buy this one

Luckily I have a spare, so no need.

I can never remember which years can use the ACDelco and which years can't. I had a spare ATE that was an exact match for a failing one on a friend's '89 XJS V12 so I sold it to him.

The 1988/89 sedans use a front mounted engine driven pump for the brakes and rear suspension (if fitted).
They have an accumulator mounted to the frame rail under the car.

The 1990MY> car use the electric motor driven pump and accumulator.

We’ll see how it goes. I’d imagine parts at JCP move a bit faster than the local dealer or regional warehouse, so I’m hoping it’s not too old.

I like the price of the AC Delco, but I like knowing the Jag part is exactly the right spec, and not a compromise. Nitrogen charge pressure and accumulator volume will be exactly the same as original which makes me feel good and reassured. It might sound silly, and I’m no purist, but that’s just how I feel about the brake boost system.

The original lasted 28 years under daily use; If I can get even 5 years out of the new one I think I’ll be happy.

So the new accumulator is in! Easy peasy after breaking the old one free. My Jag guy told me to support the bottom of the assembly to prevent damage to the rubber mountings, and that it’ll be on tight. He was right! He also said that sometimes they have to put the whole assembly in a vise, which luckily didn’t have to do.

Here’s what $236 gets you from JCP:








Works like a charm!

I can not tell you how many NEW OEM parts I have ordered from JCP that are ***cheaper*** than what US sellers want for *****used***** parts on eBay or even listed here on the marketplace. I own a XJS, E type and a X type daily driver, so I am not sure if my experience applies to the XJ40’s, but I have quite literally came across an ad for a seller that wanted 90 dollars for some used boot/trunk plastic trim (!!!!!!) for my XJS, that I ended up getting delivered from the UK from JCP new for 12 dollars total. JCP is the best resource for Jaguar parts at a reasonable and fair price.

Hey Larry! My XJS needs an accumulator so Im thinking about buying one of these. This should bolt right up, correct?

I think the accumulators I used on our '93 XJ40 were made by Ate (Alfred Teves company), but there are many accounts on the forums of late XJ40 owners using the AC Delco part 25528382. This is a different part number from the one in Larry's link; perhaps the old part number was superseded?

Larry, can you illuminate us?

Cheers,

Don

Oh boy! I really don't know.

It seems like it was a long time ago and I never bought one. Still have a working (I presume) spare off parts car and my original one, although past it's prime is still OK ...

Sorry lads, not much help

See the second post from the top in the thread at the link below. Bryan N owned an XJ40 for many years and knows his stuff, so I consider this gospel:

https://forums.jag-lovers.com/t/xj40...stion/281392/2

AC Delco 25528382 should work, if you can find one. I just searched it at gmpartsgiant.com and it comes up as discontinued and no longer available.

If I recall correctly, this accumulator was used on the Buick Reatta and possibly other GM models, so that may be another way to find one.

Cheers,

Don

The part fitment filter at Autohausaz says that accumulator won't fit a '93 or '94 XJ6, but that doesn't necessarily mean it won't. However, in all the years I've been messing with XJ40s I don't remember anyone finding an accumulator that fits a BMW that also fits a Jaguar. That doesn't mean it doesn't exist, it just means the catalogs and other reference materials are unhelpful.

With some research, it might be possible to discover the mounting thread and pressure capacity of that Ate accumulator. The price is definitely better than what many sellers want for the ones known to fit Jags. Somewhere in the forums I seem to recall someone having measured the thread of the XJ40 accumulator, and I seem to recall the pressure capacity was somewhere in the range of 1,250-1,450 psi. I think the rating is given in bar in the power hydraulic system manual.

Cheers,

Don

FYI, the Range Rover P38 accumulator works perfectly fine, in a 40, also they make them new and they are half the price. They are 50ml bigger too compared to Jag one, 0.25l vs 0.3l.
