Front brake calipers

Just before I had my ATE calipers re-built proffessionally a few months back, I found ATE.com in Europe only. They have all the parts you desire..If I had lived in Europe at the time, I would have done them myself..good luck..Jacques

 

Can you still get the dust shields for the outboard end of the pistons? Do F-dealers at least sell them? I will be do for a set soon.

I believe that the calipers are the same as on the Testarossa. Worth investigating. Hope this helps

Although the inner caliper body assy.'s appear to be the same, there is a difference between the 400i's & Testarossa's outer body assy.'s in that the 400i has dual feed fluid lines as opposed to the single feed Testarossa's. Moreover, specific part #s are rendered for the 400i body parts whereas the Testarossa's are given the plain old ATE, so not able to verify via part # comparison. Obviously, this warrants a phone call which leads me to.......
I've on several occasions e-mailed Eurospares for parts requests & have received NO replies. I figured that with e-mail, they could check them at their leisure when they have free time, and avoid interrupting them (via phone calls) when they're on a roll doing whatever. I guess if someone's manning the phone full time, that's one thing. But in this day in age of multi-tasking, those blasted phones can be a real pain in the neck. E-mail removes all the hassles, pulls all the stops! I got tired of attempting to reach them that I resorted to letting Dennis McCann handle my orders and guess what? Norma hasn't received call-backs from Eurospares after several attempts either---What is with them?? McCann's going to look elsewhere.
Everybody advertises 80,000 parts in stock but 'none' for us 400 owners!! I'm talking Real parts, not oil filters!

 

Hi Peter.

I have a very early (1979) 400i which has 4 piston 42mm calipers on the front.
I believe that they were fitted from new.
Were you able to ascertain what brake seal kit will fit the 400i (42mm) caliper?
I have had no joy in finding anything else that these 4 piston (42mm) calipers were fitted to. Any advice you may have will help!

Cheers !

Thanks Peter,

Great info.
Did you ever determine if the 4 piston, 42mm calipers as fitted to the front were a factory fitment or were they a later replacement/upgrade?

Cheers !

Rick.

 

Hi Rick,

I know I read somewhere that the late series 400i's had 42mm calipers but I can't find it. Your car was not a late series so my guess is that they've once been swapped for better brake feel.

I suspected that the 4 pot 42's might use the same parts as the 2 pot 42's. I still think that's the parts you need. At least that is what I'd opt for

This ATE caliper was used on many BMW's of the same era. The difference is that Ferrari added a spacer for the vented discs. I believe the calipers may actually be on BMW 2002. See if they are 4-pot and they may be right.

When I bought specialty pads for the front they sent me BMW pads that were too thick but otherwise identical because the BMW did not have vented discs.

I will try to check my notes and let you know which BMW it was from.

Hi all.

Just a final note to advise the mystery of the 4 piston ATE 42mm brake calipers.

As stated previously, my 1979 400i has 42mm brake pistons on the front brakes (and not the 40mm pistons as is usually the case).

I contacted ATE and they confirmed that some 400i were indeed fitted (from new) with the 4 piston 42mm calipers. It would appear that these calipers may have been a very small run and specific kits for these bigger brakes are no longer available.

Note that Moserpe previously advised that "The solution for the front calipers was the following repair set from ATE: 2M4-42, part No.95691531".

I just wanted to let our members know that when looking at a front brake caliper rebuild, be aware that some cars may be fitted (from new) with 4 piston 42mm as against the normal 40mm.

(I understand that the Testarossa from the same period also had 42mm brake caliper pistons but that the calipers are not the same as the 42mm calipers fitted to some 400i).

Hope this info may help.

Cheers !

Don't know if I ll need it one day but in any case, thank you for sharing!

 

Hi everyone, Im rebuilding front calipers for a 1979 400GT that is 42mm ext diameter. I was unable to find the repair kit, where did you guys found it
Regards
Andres

 

I found this part but I dont know if it is the correct

If you guys know the part number for the 42mm piston I will appreciste it

I undestand that must start 13.0441 and then the 42 is the piston diameter, but the 2 final numbers are a mistery for me

Good day Andres,

There have been a few threads on the brakes and so take a look at these, as the seal kits from BMW's, etc of the same era are applicable.

Here are some threads that you might find helpful:

Also, Superformance sells various bits for the brakes as well, but are a bit pricey:

Hi Sam thks for your reply, all the liks has reference to 40mm diameter pistones

What I need is where to buy a 42mm diameter service kit or the part number for ATE service kit
