Brembo has issued a large scale recall of its PR16 radial master cylinder.
This master cylinder is often seen paired with the company’s popular M50 calipers and has come as factory standard on many motorcycles.
The recall is due to the manufacturing of the polymer piston (polyphenylene sulfide), which due to the injection process, creates a porous material that can crack under certain circumstances like track use, frequent ABS intervention or even a tip over. A failure of the master cylinder could result in a loss of braking force or a complete brake failure which could lead to a crash. The remedy for the problem is a replacement piston made out of aluminum instead of a polymer one.
At the time of this writing, the recall is isolated to the US and affects two models of Aprilia and six Ducati models:
2016-2017 Aprilia RSV4
2017 Aprilia Tuono
2015-2018 Ducati 1299
2015-2018 Ducati Monster 1200
2015-2018 Ducati Multistrada
2015-2018 Ducati Panigale R
2017-2018 Ducati Scrambler
2015-2018 Ducati xDiavel S
