So apparently the brake booster in my R32 GTS-t has died. My mechanic informs me that they are 1000+ from Nissan. Furthermore 2nd hand units are generally dodgy because they are left in the elements. A brake specialist has also said he can have alook, but they generally can't be repaired and wont be able to quote me until he's had a look etc etc. Has anyone else had one of these things die? Is there any good solution?
