My 2007 Gen 4 SWB DiD has started with a screeching sound from the right engine when braking. According to independent service adviser, seems to be the brake booster/accumulator.
A new unit from Mitsubishi is R59000.


Any advice on the matter?
is it necessary to replace the whole unit or can only the accumulator (im guessing its the silver cylinder) be replaced?
If so, does anyone know of a place to get the part for cheaper?
Any assistance will be much appreciated.
Regards
Jacques
