| A_221169_TC_EN | 2023-01-10. Service bulletin. SERVICE BRAKES. We hereby inform you that with regard to the rear brake system on the vehicles in question, in the event that an annoying noise occurs during use, which can be presented as a low or high frequency whistle, this can be eliminated with the operation described below. • For the high frequency whistle it is necessary to check the presence of the antivibration plates located between the pads and the callipers. • For the low frequency whistle the problem is due to the presence of play between the slot on the fixing plate of the rear brake caliper and the anti-rotation pin; this play must be eliminated by pre-loading the rear brake caliper support plate clockwise. |
