UNI slave cylinder

[Steve Dean]

Hi Guys ....... we are doing a bunch of stuff on my car right now, it's basically an MDA based car that was built 2009-2010. The gearbox is a UN1 with the clutch slave cylinder mounted directly above the transaxle very close to the exhaust collectors. It has an ally plate covered with heat cloth above it to protect it from the worst of the heat. We are probably going to have to remove all of the exhaust bunch of snakes to get to the slave cylinder bleed valve and therefore it seems sensible to replace the slave cylinder once we get to it (it's been living a hot life for over 15 years !).
Does anyone know what make/part number the slave cylinder is? It is a Chris Cole supplied UNI.
For your info I've had a chat with Andy at Tornado (he acquired all of Chris Cole's stock) and he's got lots of slave cylinders BUT he says they are not all the same!
Any input gratefully received.
Many thanks
Steve.

Google Renault 21 turbo slave cylinder. You may only need a repair kit with the rubber parts.
Depending on what clutch you have many have been sleeved down to 22mm to match a 3/4" master cylinder.Check the bore size on your slave cylinder. I got mine from Chris Cole many years ago as well as an uprated release bearing carrier and bearing. I used an AP clutch.

Never had clutch operation issues on my GTD with the same clutch cylinder protection set up as yours. Many many miles done. Fluid change makes sense though.
