Some stupid questions from a really smart guy...

[Mike Bellis]

Send your calipers to PMB Performance and have them restored. They will be perfect! www.pmbperformance.com

Does PMB do them for free because that's pretty much what my budget is right now.

I'll have to figure something out in the mean time and replace them / send them out later.

I plugged up the gaps in my heat-exchangers with Quicksteel and the hope that it will lead to better heated air transfer to the cabin.

If you should do this yourself, you need to ensure the housing is in the stock position or it will not align to the mounting holes in the engine case. I somehow made it work as I wasn't too far off.

I also replaced the starter as the one I had was toast.

Mike,

I did a significant amount of searching for brake options and there was nothing that compared to PMB.

My GF bought me their rebuild kit for my Birthday and it arrived yesterday. It looks like a lot of work but it is by far the best option aside from having PMB build them for me.

I am thinking about painting them but not sure yet or what color. They sure do look purdy as is though.

[frank]

Well, I finally got around to tearing down my rear brake calipers to start the U-Do-It rebuild from PMB.

It has actually been a fun project.

My pins are all mismatched and 1 has the wrong OD.

Does anyone know where I could get replacements? The only place I found was in Atlanta and they want over $13 plus shipping per pin.

I will check with PMB today.

One of the pins in each rear caliper is too fat. That was done on purpose, I think to make sure that the pads went in the correct way. Unfortunately, pads with one larger hole have been NLA for quite a few years, so the typical procedure is to drill the one hole larger.

I don't remember if the fatter pin goes in the upper or lower hole, but it should only fit in one.

PMB has everything, most especially a very thorough knowledge of these brakes. Eric shouldn't steer you wrong.

Although the pins are mismatched, I do have an original top pin with the fat sections in the pin for each pad and another fat one but it's only fat where it seats into the caliper; the rest of the pin is thin so maybe it rattles when driving or shifts when braking. I ordered some new hardware for the front brakes but I will see if they fit in the rears when they arrive.

So... finally I finished the rebuild in 3 easy steps:

Step 1: Remove, disassemble, and organize



Step 2: Clean, Paint, Reassemble, and re-install







Step 3: Admire









Security system & quality inspector:



I was really on the fence about painting them. The PMB Performace U-DO-IT kit has a nice finish and I thought painting tiny calipers would be cheesy. I would also have to match the fronts but I ultimately convinced myself that it's just paint and they can be stripped pretty simply. Once I decided to move forward with painting I was on the fence about the color Black?; Why bother, they can't be seen... but having a gloss finish will keep them clean... and maybe they can be seen particularly if I put red Porsche lettering on them... but there isn't much real estate for that. Body color?; What if the color doesn't match... why illuminate such small calipers? Screw it... now is the time to paint while all the rubber is out, I don't have to hassle with masking, and since they are disassembled it will come out looking clean with no overspray.

I am pretty happy about how they turned out but now I need to paint the fronts too.

I still need to purchase and install pads... the ones I purchased at my FLAPS had a little metal shim to the sides of the backs that would have caused them to shift when the caliper pushed against it. I will have to order some from our host.

Looks nice

You can use a small bit of Curil T on the bores. This will guarantee they will never leak.

I think I just may try Curil T as it's high-heat and doesn't harden... I think after installing my o-rings I may have a leak on one or two of the tubes.
