M caliper rebuild kit problem

[Eduardo Castrejón Elbjorn]

Hi,

I bought a complete 72 911 front suspension with M calipers (3 " space, iron).

My calipers are this:



I bought to Pelican the rebuild kits but are huge for my caliper pistons:



The caliper kit is:

ATE
901 351 964 11
Front calipr rebuild kit, steel M, 911/912 (1965-75), 914-6


What happened here ?
I really don´t have idea
Please help me
Regards

Hmmm.... Could they be rear 911 brakes? Those have different piston sizes than the fronts. I forget the exact sizes, though!

Ahh, here we go. Mr. Anderson sez: Rears == 38mm dia. pistons. He doesn't say what size the front pistons are, only that the rears ones were smaller than the fronts.

Eduardo,

I purchased 2 of the front brake caliper rebuild kits from Pelican. When I checked inside the blue boxes, they were different sizes! I sent one back.

I now have two the same. I hope I sent the correct one back, they are still in my garage waiting for that particular project to start.

Dave:

Thanks for your answer

Yes, my pistons are 38 mm

Then, Do I have rear m calipers ?

But I don´t have any mechanism for parking or emergency brake, then ?

Andrew, thanks for your answer, I will investigate this.

The 911 rear brakes used a separate drum brake mechanism. I suspect you have 911 rear brake calipers there. Not certain, though.
