Hi guys, Do you know where I could buy a replacement for my f355 brake accumulator ? Seems the original one is no longer available. Thanks Joe Sent from my iPhone using FerrariChat
You can cross-reference it to other mfgr parts (it's not Ferrari specific) or you can buy it from superformance. Sent using FerrariChat.com mobile app
Hi, Thanks for advice. I bought one from Superformance. However, the dimension seems not right. The height is higher than my original one. I m wondering if anyone install the after market one from Superformance or which after market one could fit properly.

Certain Jaguar models used the same Teves brake master. I bought a Jaguar accumulator, same as the original Ferrari.
Some Range rovers used it as well as some Thunderbirds and Regals and Reattas. You can find them on ebay, takes a bit of cross reference for ford, gm, jag or range rover is all. I did it awhile back and found a slew of them but did not keep notes. Some were compatible some absolutely identical. I do believe people rotate the unit to get it to fit btw.
Found these in my history, jsut a few https://www.powerbrakeservice.net/bracforlimav.html https://www.amazon.ca/ACDelco-25528382-Original-Equipment-Accumulator/dp/B000C9LTRC https://www.kirbanperformance.com/news/89/8-18-10+Inner+Circle.html https://www.tbscshop.com/1987-1992-thunderbird-sc-mark-vii-abs-new-hydac-accumulator-ball/ https://www.amazon.ca/ACDelco-25528382-Original-Equipment-Accumulator/dp/B000C9LTRC Try rotating the unit first. Found this it was noted that nonperformance one is the wrong size. That tells me other places may have the right size. https://www.ferrarichat.com/forum/threads/95-brake-accumulator.575304/#post-145991949
Hi guys, thanks for the information. The other concern is that the workshop manual said the pressure should be 80 bar inside the ball. Do you guys know of the cross reference ones such as Jag’s one matches the pressure requirement ? Thanks Sent from my iPhone using FerrariChat
The pressure is up to 180 Bar. Jaguars (XJ40) had almost identical ABS Master and ABS pump as the Ferrari 348/355. The Jag ABS pump operates at similar pressure as the Ferrari one and, in fact, a bit higher - up to 195 Bar. Image Unavailable, Please Login
Search the archives. I replaced mine like two years ago. I was going to go witht he Jag replacement, but second guessing said the Superformance should be a known good alternative. Wrong. It simply doesn't fit being too large. They did take it back & said they would unlist it as a proper fit. I guess they didn't unlist it. Then I went with the Jag from earlier posts as well as the GM switch to stop the accursed ABS lamp on problem. Both fit perfectly and haven't had a single brake problem for 2 years now.
Guys , thanks for the information. I will try to see if Superformance accept my return first. Sent from my iPhone using FerrariChat
Superformance accepted my return and gave me a full refund. And I bought a Jaguar one and it works ! Sent from my iPhone using FerrariChat
Unfortunately , I encounter another problem. Whenever I cold start the car, there’s no problem with the abs light as well as brake light. That is when I turn the key “On” (engine not running) the ABS light and the Brake light go off in few seconds. Then I turn the key to “Start” (engine running ) , ABS and brake light go off too. Everything is just fine. However , when I warm the car up and drive for 15 mins. I turn the key off and then re start the engine , the ABS light goes on and stay on. In addition if I press the brake for like 8-10 times , brake light goes on as well. And then both 2 lights stay on forever. Seems the abs pump is not working when engine is running. Then I shut down the engine , turn the key to ‘On’ , abs pump is running and then both brake light and abs light go off after awhile. But abs light is on again when I start the engine. This only happened when the car is warm up. Never has problem in cold start. Do you think it’s a relay ‘s problem ? Thanks Sent from my iPhone using FerrariChat
My mechanic changed the brake fluid of the whole system. I think he did it properly. Sent from my iPhone using FerrariChat
Hallo, I have change my accumulator with a new, but now the pump start each time I press the break. I have no bleed the system after change accumulater. Can that be the problem?
The first time i changed the whole pump assembly and bleed the system with the old accumulater. I bought a new accumulater, because I can only breack 3 times with the old. But with the new, I can break only one time. I resend the new bulpto the seller and he gives me another, but the problem is the same. Is aire in the system? Thanks
It's not air in the system. There is / are pressure sensors attached to the pump (that green thing) as well attached to the Teves unit that control when the pump is on. Did you get a new or old pump assembly? Did you swap the pressure sensor for a good known one? Did somebody fix this before you? Did you check the wirings at the ABS unit and fuse/relay unit?
I have change only the pump wand the e motor. The pressure switch is the old. I have also change the relais from pump and the level measerement (orange). That what is strange, if a try with the old accumulator, it goes for 3 times and with the new only one. It seems also that with he new accumulator, the car breaks better as with the old accumulater, but the pump charged each time
It is the same at the old one and the description are also the same. I try to bleed again this week end and tell you, if it is ok or net Thanks
If you have air in the lines to the rear brakes, it will cause much more than normal of the pressurised fluid in the accumulator to be "consumed" on brake application. This is because a lot of fluid from the accumulator will be used just to compress the air (equivalent to the brake pedal sinking on conventional brakes when there is air in the system). You will need to keep the key in ACC position (fluid pump active), especially when bleeding the rear brakes.
Hallo, I bleed again the whole system, and nothing change. The pumpe start charging each time I push the break pedal. It is possible, that aire is in a other place ?
