Recently I purchased a used 2011 V7 Classic with 3500 miles (practically new) on the odometer. The bike failed Maryland State Inspection due to the rear brake disc having a thickness of 0.157” (4mm) being 0.02” (0.5mm) below the 0.177” (4.5mm) specification minimum.
The inspection station (Pete’s Cycle) didn’t have the material readily available and had to call another MC dealer for the information and perform metric to imperial conversions.
The service tech told me that OEM Brembo brake pads are unusually hard and that could be the possibility of the excessive wear on the rotor. Changing to EBC brake pads would fix the problem.
After going through the owner’s and service manual’s the only information concerning the rear disc that could be found was the diameter, not the thickness. The Guzzi bulletin boards I checked more or less said the same thing about the brake discs being proprietary information.
Finding the OEM disc online was tricky and yielded no information on the depth. There was one aftermarket manufacturer in Australia that had a disc for sale and the thickness was listed at 4mm which is the exact same as the measurement on my bike (<4K miles)!
Before I spend $300 on a new disc with installation, what are the factory specifications for the rear disc brake on my 2011 V7 Classic?
Any help getting this sorted out is appreciated,
Andreas
