No, I don't have a copy of the service manual unfortunately. I think I know how most stuff should work, although the routing of the lower tension spring isn't entirely obvious.
Pulled the trigger on some new pads as well. Figured I might as well do everything while I'm at it.
Yeah, I find with these bloody cars it's the last 10% of the info where the cream is. I have lost hours to that sort of stuff.Pulled the trigger on some new pads as well. Figured I might as well do everything while I'm at it.
Yep that's a proper mess!
Horrible job but helps with the right tools and decent spring hook / puller.
From memory I used this

Update on the failed handbrake shoes. Both sides of the car now have new handbrake shoes, pads and discs.
The handbrake shoes aren't the worst to do, just awkward. The lower spring is the only bit that gave me much trouble, partly as the old one had been taken out by the shrapnel from the old shoes and so I didn't have it as a reference for refitting. I could have looked at the other side, but as I had jacked the car up hard to one side of the garage, I didn't have space. Anyway, even the workshop manual doesn't show clearly how it should sit so for anyone who might do this, below is the pic I couldn't find, showing how it should look. For the side springs, these make them a doddle - https://www.toolstation.com/irwin-vise-grip-lockin... The bottom spring should be done first with it linking the two shoes, then the sides and then the adjuster gets put at the top and the top spring fitted - easy enough with a pick.
Interestingly, the shoes on the other side of the car were absolutely fine. I changed them too as it made sense to do everything and I had the parts. I have a suspicion that the problem with my brakes was caused by.... Porsche servicing the car. In what I imagine is a bid to justify the service cost, they had adjusted the shoes so they were right up against the inside of the discs. This meant that when I picked up my freshly serviced car, the handbrake would hold the car on a 45-degree slope on the first notch. Great, but it also meant that there was excessive rub of the shoes on the disc when the handbrake was off which will have generated lots of heat. Plus when they got wet they would rust on badly with lots of force being put into the shoes when I tried to free them off. I've adjusted the new shoes so you need to pull the handbrake a little further but the result is the shoes aren't excessively rubbing.
The rest of the brakes are straight forward. I didn't need tools to press the pistons back, they moved freely with a squeeze. Interestingly, the pads that came out which are only about 30% worn were not in especially great shape. the inner one had some surface deterioration so I'm happy to have changed them. Might do the front pads and discs too, just so it is all done.
I reused the wear sensor that were there and the pad retaining clip and just cleaned them up with brake cleaner and a wire brush.
Hopefully all good now, especially as the weekend weather is looking a bit warmer and drier than the last few weeks - time to bed the new brakes in and put some miles on it.

Looking good indeed. I was there a few weeks ago. What tyres are you running and session times / how many laps? I had a brilliant (dry) day but did have a scary moment, Wonder if i went to long on the session on standard Michellin pilot sports.Bedford & Anglesey next !

It’s on Cup 2’s. Track geo, front spacers. They are very stable for about 15 mins hard use, say 10 laps or so, it does squirm about a bit more after that but they hang on very well. I got it hooked up lovely a few times over the crest at Avon rise, full oversteer slide on the brakes, and rotate it into quarry all in one smooth transition. Bloody brilliant when you nail it, you feel like a hero. Bit scary when you screw it up
Thanks, i need to invest in some cup 2's, best place to buy? Couldn't agree more. What sort of speeds were you reaching down the straight before braking for Avon rise? Im no driver and still learning. Have had some tuition but need a lot more ! I found a huge difference between say late braking and reaching around 130 mph and getting a bit out of shape before turning into quarry and braking a bit earlier 123 mph & keeping it all tidy, turn in correct etc etc. My moment came on Old paddock bend (Strangely) just after the Esses. Still no idea what happened !!!
Had my Geo done at Center gravity, Have you got 7 or 10 mm spacers, make much difference ?
Got any others booked up ?

I get most of my tyres from Camskill Tyres, mainly because the service level is very good.Couldn't agree more. What sort of speeds were you reaching down the straight before braking for Avon rise?

I have no idea what speed I am reaching before Avon Rise its right at the top end of 5th in my PDK car. I never look at speeds I am concentrating far too hard on the track and where I am going to look especially at the end of a long straight. That's how accidents happen. The bigger impact I found on getting Avon Rise right was not so much the speed as you turn in but the position on the track, I was inching further and further over to the right on turn in to try and straighten the line through. However there is a very clear point where my car just did not like any more and would spit the back out really quite hard, which was a bit scary! I think there may be a bit of a bump if you go too far over. After that its just a case of trail braking through the slide until you can turn into Quarry. If I am struggling to slow down for Quarry its not a huge problem it just means that I turn in too late and miss the apex. I think I only got it bang right once or twice all day
A good driver must be a joy to watch through there its a great sequence and very challenging to us amateurs.Ah yes that Esses wasn't there last time I raced at Combe, 1986 I think, I nearly missed it first lap round
I must say I never had any issues at all with Old Paddock Bend, not sure its that popular for crashing on either? Just put it down to funny turn and forget about it. Odd things do occasionally happen when you are chasing the limits.I think my spacers are 5MM but they might be 7mm. They did need longer wheel bolts. They significantly improved the turn in, reduced understeer and improved feel and confidence. Most noticeable for me down Craner Curves at Donnington where it was night and day better into the left hand bit. Cheap mod so well worth it.
Got a few booked but not sure which car to take where. The R was down for a ring Trackday in July but I suspect that might not happen now, its also down for Anglesey 23 August. What is your schedule?

Appreciate the feedback. In the R i have only done Pembrey & Combe so on a steep learning curve. As you say it is so nice when you get it right which unfortunately is infrequent ! I only made a reference to speeds after easing myself back in after my 'moment following a group of other cars attempting to get lines correct. Quarry can definitely be driven many different ways and takes a lot of practice. There is not much room for error between avon rise and turn in for quarry.

I wouldn't say staying out to right is correct line into quarry. I find it's a very early turn in an no braking or trail braking until you line up with the traffic light and then it's hard on .. It's not my best circuit tbh but have competed there a few times. I am going by memory as it's a while since we went there but there's a change in the tarmac which was my drift over to apex point.I have no idea what speed I am reaching before Avon Rise its right at the top end of 5th in my PDK car.

Aye I am sure that you are right, that’s what I found by trial and error 
Not sure that no braking until after Avon Rise would work out too well in the Cayman, it’s carrying quite a lot of speed in and on road tyres, different matter on slicks mind. Funnily enough it’s probably not that important a corner in terms of the overall lap time, Camp corner is way more important.
Live on the Isle of Man but have a bit of a base in the Midlands. Which is handy.

I didn't mean to sound disparaging please don't take me wrong. It's not a circuit I've done a lot at so I could be completely wrong. I have gone over Avon Rise and into Quarry with just a lift on slicks and R888R's, Maybe standard Michelins or N1 tyres are different but I'm sure in an R on a decent tyre it would be similar. I love the IOM we went over in 2019 to do the Manx Classic, pissed down all week but it was till an awesome event, I have been there as a spectator and competitor several times and I love the place and the people Not sure that no braking until after Avon Rise would work out too well in the Cayman, it’s carrying quite a lot of speed in and on road tyres, different matter on slicks mind.

Great pics there and to hear about Combe; the first time I saw a Cayman R was at Castle Combe. The owner was over from the Channel Islands in a lovely Peridot for his first flying drive; I seem to remember him saying he loved the car but was a bit disappointed with the brakes. I was impressed anyway; wanted one ever since & just achieved this last couple of weeks!! It’s a good fun circuit, must get there again.. First proper spin in mine at the weekend. What an amazing car; much more nimble and up on its toes than the other 987s I’ve had.. almost feels like my old S2 Exige, but in a much more grown up & highly developed way.
I can’t stop looking at it and wanting to drive it! The car has been well loved, thanks to previous owners.

Lovely looking car, is that PCCB’s hiding behind the wheels I can’t stop looking at it and wanting to drive it! The car has been well loved, thanks to previous owners.
wish mine had them, just for the weight saving and better brakes. Standard steel brakes are a bit limp for circuit work but very easy to upgrade, not sure about ceramics on an R but there are no doubt lots of people who do. They are a lovely car and much more than the sum of their parts, which is typically Porsche. I have had lots of Casters over the years including 981 GT4 and currently have a 718 Spyder. However it is the R that is the pick of the bunch. I love the fact that it doesn’t shout “race car” wannabe, and is so small and delicate looking, I love the feel of driving it, the steering, the LWB’s, the tautness of everything, the precision. The engine is a gem. Not much not to like really.
Happy days.
Cheers BM; yes PCCBs 
. The car stops on a dime; they’re incredible! I’m really looking forward to getting it on track. I’m no racing driver and just out for fun so I’ll definitely enjoy putting the Porsche engineering to the test... hopefully they’ll take my efforts
Like the term Casters.. v good
As you say happy days... time to enjoy
