Aprilia RSV Tuono Rear Brake Recall

Aprilia RSV Tuono Rear Brake Service Recall / Aprilia Service Recall 009-2007

The rear brake lever stroke gets longer due to some air residues within the circuit this results in frequent bleeding being required. We carried out some analysis and tests and concluded that a standard bleeding procedure could prove inefficient. Following are some preliminary inspections and a bleeding procedure to be performed in two different steps: on the calliper and on the master cylinder. For this operation, you will be granted the labor time and intervention shall be entered in the GGP system.

• Preliminary Checks
  1. The brake master cylinder installed on the vehicle should be equipped with fitting part no. AP8133872 and brake fluid reservoir part no. AP8133873 that are standard equipment since the end of 2004. To ensure a correct air bleeding, both the fitting and the hose connecting master cylinder and reservoir must be 4.5mm of diameter. (For further details, please refer to technical note no. 16 issued in 2005)
  2. Check brake master cylinder peg clearance. It should be between 1.0 and 1.5 mm. For measuring and restoring correct master cylinder peg clearance, if necessary, please refer to the following procedures.
• Adjusting Peg Clearance
