Hello, Fellow Addicts!
As promised, we’ve been keeping an eye on developments related to the #Brembo Master Cylinder #recall
As we mentioned earlier in the week, the reported fault seems to indicate that under heavy braking pressure, such as heavy braking during mountain carving, or track days, the plastic internal piston Brembo decided to use in the PR16 Model, may crack. The PR16 MC is usually mated with the M50 Caliper.
Brembo has admitted that they used a ‘polyphenylene sulphide’ plastic piston and for now they are agreeing to replace the US recalled units with an aluminium version. There is no word from Brembo on recalls in other countries.
As mentioned in our last post on the issue, should the piston crack, front brake pressure will be lost and brake fluid can also leak out of the unit and spill onto the bike. We all know what brake fluid can do to a nice paint scheme!
Here is a crude schematic of a motorcycle master cylinder. They vary in design slightly from one bike to another, however this should give you an idea of what this piston (circled in red) looks like.
Those of you watching know that so far the recall is only in the US. However, due to the potential danger, affected owners in the UK, Canada and Australia are understandably worried.
Some other media outlets have speculated that perhaps Brembo only used the plastic piston in the PR16 MC’s destined for the US market and sent aluminium piston equipped PR16 units out to the rest of the world. That could be possible. However relaying on this speculation could be quite costly for potentially affected owners. After all, failure of the PR16 could spell serious injury or worse.
The fact is, these things are mass produced on an assembly line. Efficiencies and cost usually dictate that the same internal parts are used in the same unit regardless of where it is going. Brembo likely used the plastic part to save costs, since moulding plastic is far cheaper than using aluminum.
Unless there is a law within the country it is being shipped to which dictates that part must be of a certain quality or material design, manufacturing efficiencies dictate keeping the units identical. So our more conservative guess is that its likely that all the PR16 MCs are made the same way.
So it is a global problem, why only a US recall right now? Well, when it comes to recalls, how they are done depends on the country. The US has a centralized National Highway Transportation Safety Authority (NHTSA) and they have a centralized their recall system, and that system works very quickly, and mandates that all manufacturers, distributors, and vendors of the part in question immediately address the issue. In other words they have a strong legal mechanism to sort the issue out fast.
Other jurisdictions often don’t have that and rely on the manufacturer and distributors to make their own announcement about the product and deal with remedies as they see fit. So in Australia for example, owners would have to wait until the distributors for #Ducati #KTM #Aprilia and #Triumph to consult with the manufacturers in England, Austria, and Italy, and wait until they are given the word that a recall is in play. Then they would have to send word to the dealers or issue letters to affected owners to get the bikes in.
When you have different companies with different internal protocols at play, and a recall system is not centralized, then news may come at different times.
Further, until the distributors are officially told about a recall, they will simply say there isn’t one in play. Why? Well, they can’t speak for Brembo, or the manufacturer. They don’t have that authority. They are limited to passing on information from their upstream and not contradicting it.
Also… In the crazy world of litigation, if a company knows about an issue (for example an employee of a dealer or distributor) and admit to it, but don’t do anything about it and a loss is suffered (money, injury, death) then that company would be held liable, since they ‘knew’ of the issue and the courts may rule they had a duty to resolve it. So for this reason as well, the official word has to be kept. Even if there are murmurs behind closed doors in the mechanics bay.
In short, while we cannot be sure that the PR16 on worldwide bikes is at issue, we at Motorraddicts think that potentially affected owners should be wary of the problem and keep themselves updated.
So if your bike lands in this list, or you upgraded your MC, or your bike is equipped with the M50 Caliper, then keep an eye out, inquire with your dealers, and if you are really interested have a licensed mechanic open the MC up at your next service and see if the piston is made of plastic.
The USA recall (NHTSA Campaign Number: 17V812000) says that the following models are affected. (This recall is yet to be updated with the Triumph or KTM data)

For Aprilia Owners it seems that the Noale factory is indeed issuing a recall for their European bikes. If you want to check if yours is affected, visit this link and enter your VIN number for confirmation.
We will try and keep you updated on the issue as things progress. Until then stay upright, and keep your throttle hand strong!
