The part number for the slide repair kit is on PET 602-01 & 603-00. The repair kit give you new slide plates and the respective screws.

Front = 964-351-959-00
Rear (C4 - 4 piston)) = 993-352-959-00
Rear (C2 early - 2 piston) = ?? <not listed in PET>

Thanks Rob - I appreciate it - I'd like to just buy the Cap head screws though - since the plates are stainless - they should be easily re-usable - but the screws look to me like I'll chew them up getting them out - so before doing that, I need to source the correct cap head bolts for all four calipers.

i read on the 928 forum where guys needed alot of heat to loosen the loctite 270 (high strength) in order to get those bolts to budge.

but if I have to spend hundreds to get the plates, just to get the capheads, then I'd be better off sending the calipers out for full rebuild and paint...

Rocket Rob

That's my understanding too. You need an acetylene torch to heat the screws. As for the cost, I checked Sunset Porsche, the slider kits are $37 each.

didnt sunset open an online ecommerce site? not that I don't want to call and talk to bob - but sometimes its just easier to shop from my phone with no one listening...

Yes, they have a website. Its http://www.porschepartshub.com/

so I called Sunset - they cant sell the Cap nuts for the caliper spring plates separately - 37 is a good price - but there are two per caliper and so thats 37 times 8....which when the spring plates are perfectly fine, it's silly to spend the money. so on to McMaster Carr for stainless cap nuts.

Question is - does anyone know the exact size of that metric cap nut? looks like an M8? and then length? its not listed in PET. Maybe I need to call Brembo....

Mr.Alex

How did you check on the pistons Goughary? Just press pedal and watch movement?


Side note; going to swap the steering rack bushings tomorrow; the work manual is somewhat confusing. Is the clamp that holds them considered the "Steering Gear to Crossmember" mount, which is 33ft lbs of torque. Or is it 17ft lbs?

Goughary

Alex I pushed the Pistons back and they moved...so I didn't really check them. The seals look fine on first inspection. At some point I'll have to pull the seals out and do all that. But the clear thing here was that the pads were dead stuck on one side. Impossible to move or to remove from the caliper. I'm assuming there was room enough when the calipers were hot to get dirt and funk built up behind the spring plates, and as soon as they come out and all is clean, the pads will move freely. But for now, they are sticky. The spring plates aren't worn out, so I just need to take out the two pan head bolts that hold them in and clean them up and reinstall. But there's enough info on rennlist for me to know to not take those out and expect to reuse the bolts. Apparently most times they just don't wanna budge. So as soon as I find out what size, I'll order a bunch from McMaster Carr and get this done. Hopefully before April 19 C&C...but that's not looking likely at the moment.

IIRC 33Ft lbs is correct.

Sounds right, it is 41 Nm.

Mr.Alex

Was a bit premature to ask. The very last allen bolt decided to not want to come out, got all the others loose. Will probably need to drill it out as its starting to spin.


However my main problem at the moment is getting the OEM shift components back in after I decided not to drill the shift tunnel on my own. Any tips on getting the ball cup back on the shifter rod? Couldn't quite get on it with a C-clamp, and when I tried to use a jack per some other thread on the forum, it just started to lift up the front of the car off the jackstands.

Rocket Rob

To "press" the shifter ball joints together, I found the best way was to use some long reach channel lock pliers (similar to the photo below). I would place the cup over the ball and then use the pliers to squeeze it together. It was easy once I found this method.

should I be spraying a water sealer on my top?

ThomasC2

About the shifter rod. I used my floor jack and just pressed the cup upwards.
