944 S2 Brakes

Fella's they are slider plates and not wear plates disimmilar metals creates corrosion and pushes the slider plates up and "nips" the pads.
I am in the process of a complete brake rebuild, cross drilled discs, new pads and wear sensors along with calipers re build, they have been acid dipped the powder coated (Red) just building the calipers back up ready to fit, I have had some hassle with seals as Porsche modified the calipers seals from scarper seals to dust seals, long story but looks like the right things are on the way now.
Removal of the slider plates is NOT straightforward you will definitely not get the retaining screws out with an Allen key, I heated mine with a gas torch and managed to remove a couple by knocking them round with a centre punch which took ages, gave up and eventually went to my mates garge where I cut down a couple of 4 mm Allen keys into 20mm lengths, he welded them into the dome head retainers, let them cool and then got a 4mm quarter inch drive socket on them after cooling and they came out, Brembo apply a sealant which requires some heat to help them move.
I was put on to Thomas at Pro-Calipers who was great help for seals etc.
He also does a refurb service, not cheap but they will be right, sorry to be negative but a Brembo strip is not a half an hour job on the bench believe me, I have been at mine 3 weeks now, but nearly there I they will be good for many years and look rather sexy in shiny red with Cross drilled discs.
Feel free to fire some questions my way.


 
Frenchy,

I have now got the calipers off, two of them have corrosion, looking at the plates bolts, no hope in hell of getting them out easily.

I have boxed them up and waiting comfirmation from the company who are going to rebuild them for me - need to decide if to stay with the blue or go with Porsche Guards Red ( which I am leaning towards )
 
Hi Frenchy, good comments I've been looking at BCS for a caliper refurb as I know my bleed nipples will need heli-coiling and the scraper plates will need re-seating as well. Problem is BCS quote a fairly high base price and then charge an extra £90 per heli-coil. Not sure what they would charge for any extra work on scrapper plates etc. and yes, I said £90 per heli-coil!!!! When I heard that I thought maybe I'll just do that part myself! However I don't fancy tackling the corrosion behind the scrapper plates.
Do you have contact details for your guy? To my mind anyone asking for Brembo caliper refurb on an old 944 is almost certainly asking for corrosion correction which is likely to entail re-threading nipples, unions and scrapper plates as well as the usual piston refurb...

 
Well the calipers were sent off to Custom Calipers for a full rebuild and spray in Porsche Gaurds Red. now need to sort my drivers window out and the car will be fully operable ( once I figure out how to bleed brakes lol )
 
Found the issue with the window, main cog is all chewed up at the later part so that’s why it’s not raising fully. Order a brand new regulator and mechanism for £85 - bonus!!!
 
Having your pants down at £90 for a helicoil, all you are doing is drilling a larger hole tapping then fitting a threaded insert, that said they may have to split them to do it,which Porsche recomend you do not do ?
Got my rears on today, having a nightmare fitting the larger scraper seals ,44mm ,I need to speak to Thomas at Pro Calipers who supplied the seals, kin nightmare this Brembo carry on, will get there in the end though, rather clammy in the garage this afternoon !
 
Mine are I guards red but I have the fastest colour of course.......guards red. It fits with most paint jobs though. I have the scrapers on mine Frenchy. They are PITA hence why opted for a professional job in the end. It cost me about £1200 painted but I had to replace every piston, and they gave me the old ones back for compliance and proof. They are now spot on though and have highlighted how poor the 30 year old master cylinder is. I do have the Holy grail of Turbo ABS master cylinders to fit this summer though. Max at Frazerpart came through in that one for me. Don't even bother looking. Rocking horse crap now.
 
I had my fronts done recently by a mate for a very good price, look and work great now. Rears will be getting the same treatment next year probably although they seem fine with no plate lift at the moment. I am however fitting new rear discs and pads this week so that will be the acid test!

WTF, there must be cheaper new calipers, or conversions using alternatives.
 
I am into £450 so far removal of slider plates,acid dip, podwercoating,seals and scraper seals, rears are rebuilt and back on the car.
Just about to take some pictures of my front calipers and sent to Thomas at pro-calipers as I cannot get the 44 mm scraper seals in, absolute flipping nightmare !
Discs, pads and wear sensors have gobbled up another £700 odd, but when done will be good for years.
Complete pig of a job, the Brembo components are very pricy !

Yep when you have to replace all 16 pistons it starts getting pricey. That's where the cost is in the pistons.

Rob, enlighten me on the Turbo ABS master cylinder ?

Getting hold of the master cylinders is now liking finding unicorn crap. The only place you can get them now is Porsche as they have removed the license to produce them in the aftermarket.. And guess what they pretty much charge what they like for them. Porsche are not silly I think and have started to appreciate the 944, especially the Turbo as a good cash cow for classic parts sales.

As the car drifts from cheap performance to Classic Car status the target demographic will change and evolve. Just as, back in the day, you would pay next to nothing for a 994 but be surprised that parts were quite expensive "...because it was a Porsche", we are now in the realms of "...because it is a Classic Porsche."

Porsche brake refurb kits have always been expensive. With careful shopping, and looking for offers, you could often get a new caliper for the price of a full refurb kit. I guess those days are long gone, at least in respect of 944 parts but are there similar spec later calipers which may provide the required components cheaper?
