Help - 348 Brake caliper/piston locked?

Definitely rebuild it, but if anything is scored or bad on your caliper contact me before buying one. I literally have dozens of these calipers for sale and will give you a good deal.

 

What year is your car?

Yes

 

I may have spoke to soon as I keep thinking "355". That said, look at the back side of the caliper, it will have "Brembo" on the casting if so.

 

Yep..if its ATE... that's gonna be a problem. The pics look like brembos though

I tried everything to find ATE seals (including checking sizes of ATE seal kits that are separately available for other cars, BMW, Volvo etc.) for my 348 but got nowhere. So, I decided to replace all of my ATE calipers with Brembos - 2 used rear from a 355 (same as the 348's) and 2 new front. I keep a set of Zeckhausen seals for any future replacements.

 

Apparently I don't clean the backside of my calipers very well.

Here's a blind shot of my '92 Canadian tb.

You are a lucky man my friend. Now rebuild them!

Yes, thanks. It was a sigh of relief when I saw this today.

For me, a rebuild isn't needed yet, and I'm collecting parts.

 

In the 348 there was ate/teves and brembo calipers. They were exactly the same as far as I know. There was no advantage with either caliper for racing. Later there was a bigger caliper brembo that made its way into the 348 challenge cars and some 348 racecars but never legal in the 348 challenge series. I thought the oem 348 calipers was ferrari spec so the seals should be interchangeable. But I could be wrong. I have never bothered to inspect those 2 calipers side by side. Later there was a brembo big brake kit for the 355 challenge car. I thought the stock 355's also used the same calipers as the 348 but those were all brembo. I could be wrong on that too.

Has anyone tried calling Girodisc? There are way more 348/355's out there than 550 maranellos and Girodisc has the seals for the maranellos. I would not be surprised if they have the 348 ones too.

 

I have an ATE kit 11.0441-5701.2 which is for Volvo 940 front calipers. The "57" in the part number means 57 mm diameter so the p/n that you showed is also 57 mm ("5702.2"), nowhere near the sizes for the 348 calipers - 36 and 40 mm. I do not know what the numbers in the ATE p/n-s that I have coloured blue mean but the first two digits after the dash always mean diameter.
