Aprilia is the first manufacturer to issue an official safety recall in Australia over a Brembo brake failure that also affects some other European models.
Australian company PS Importers issued the safety recall through the Australian Competition and Consumer Commission on certain 2015 to 2017 RSV4 1000 and Tuono 1100 (pictured above) models.
The complete list of Vehicle Identification Numbers (VIN) of affected bikes with the Brembo brake issue is listed at the end of this article.
Known owners will be contacted by mail. However, if the bike has been sold privately to another rider, they may not get the notice. If you know of anyone with those models, please alert them to this article.
Meanwhile, there is no word from any of the other importers about impending recalls over the same issue, despite Brembo brake recalls issued overseas earlier this month.
When we contacted PS Importers earlier this month they told us there was no cause for concern.
“Some selected units of MY15-16 Aprilia RSV4 Euro3 models are affected, as well as a very limited number of the Euro 4 MY17 Tuono/RSV4 models,” a spokesman told us.
“The information we have so far only suggests that there may be some increase in stopping distance under very extreme braking conditions.There is no suggestion of failure or an immediate risk.”
Yet they have decided to issue the formal recall notice.
The fault is possible caressing in the plastic piston inside Brembo PR16 radial master cylinder units. they are being replaced with aluminium pistons.
Brembo issued a statement that the safety recalls only affect radial master cylinder pistons in 15mm and 16mm diameters produced between 2015 and 2017.
They were supplied to Aprilia, Ducati, KTM, MV Agusta, TM Racing, Moto Morini and Horex.
The recall does not affect brake master cylinders sold as aftermarket kits through Brembo authorised dealers.
Manufacturers have been informed and owners of motorcycles with brake master cylinders affected by this recall are advised to contact the manufacturer directly for parts replacement.
The Department of Infrastructure, Regional Development and Cities told us they had contacted the Australian distributors of Ducati, Aprilia, Triumph and KTM motorcycles.
“The distributor of Triumph motorcycles has advised that no vehicles supplied to the Australian market are affected,” the department says.
“Other distributors are aware of the recently announced recall in the United States and are currently establishing whether voluntary recall action is relevant for vehicles supplied to the Australian market.
“The Department will provide further information on other vehicles supplied by these manufacturers as it comes to hand.”
There is no word yet from Australian distributors of Ducati, MV Agusta or KTM.
Brembo brake fault
The fault is believed to be a crack in the internal piston of the PR16 radial master cylinder.
The crack can result from prolonged and hard use such as track work or frequent use of ABS.
Obviously, if it breaks, not only will braking force be diminished, but owners could also end up wth highly corrosive brake fluid leaking over their bike.
Brembo says the problem is with the plastic (polyphenylene sulphide) they used. To fix it, they will replace the plastic piston with an aluminium piston.
Here is the official notice from Brembo about the fault:
The anisotropy of the piston material, in addition to potential porosity introduced during the injection process, could lead to crack generation and thus potential component failure. The failure may occur with no warning to the rider, although a significant loss in brake effectiveness may be an early indicator.
In May, 2017, Ducati received initial information from the field regarding front brake malfunction involving a motorcycle in the European market. During the same month Ducati received a second European front brake malfunction report.
Ducati initiated an investigation and began to jointly conduct an analysis with Brembo, the component manufacturer. In September, 2017, a third European case was discovered. Failure was found to have occurred during race track use in two of the three cases. In November, 2017, the investigation was finalised and the root cause was identified as above. On December 14th, 2017, Ducati determined that a worldwide safety Recall was justified. For subject motorcycles sold in the US, there have been no reports of injuries due to the defect.”
