As per the "what did you do" thread I had to source a pair of replacement front calipers today, as mine have seized on the lower inner piston on both sides.
After searching the 'net, I found a couple suppliers had them in stock. First being Torquen - albeit at over £600 for a pair for either cast iron or aluminium.. Then I found some fully rebuilt aluminium ones (the correct fitting for a TT) at less than half that, which got me thinking. Cast iron vs aluminium....??
Both seem to have their merits and drawbacks - the ali ones being much lighter, so less unsprung weight - whereas the iron ones allegedly handle the heat better, reducing the chance of disc warpage. If one believes everything one reads on the interweb LOL!
Seeing as I don't track the Zed - and I am happy with the OEM set-up, when it works properly, plus I have a set of Brembo discs waiting to go on, as opposed to the Ebay ones I had previously, I thought the ali calipers would suffice.
Opinions please - good or bad😁

OK...any sugguestions would be gratefully recieved...
Please bear in mind I am not a mechanic or a technical expert.
As I look at the engine, the middle cylinder on the left hand bank is not firing. So far I have...
Swapped coil packs around and the same cylinder still doesn't fire.
Swapped spark plugs around and the fault remains on the same cylinder
Tested the resistance on the injector..it's 12.7 Ohms
Tested the resistance on the coil pack..it's 0.7 Ohms
Tested the voltage on the injector feed...it's 13.34 Volts
Tested the voltage on the coil pack feed...it's 14.06 Volts
(The coil pack connectors are brand new)
The engine was replaced a couple of weeks ago and has been running like a dream until today. Any ideas would be very welcome...
Thanks in anticipation...
