Suzuki Master Cylinder Recall

Most Suzuki owners know the stock Suzuki master cylinder on current model GSXR motorcycles can be a bit problematic with declining performance over both time and use. There angle of the master cylinder mounted on the right hand control (clip on) does not allow for complete bleeding of the master cylinder unless you routinely remove the master cylinder assembly during brake service, to completely purge the system at the upper bleed valve.  Even with routine service and increased service intervals, the piston can corrode and otherwise be rendered less effective or ineffective over time.

THE REPLACEMENT PART IS A NEW, COMPLETE MASTER CYLINDER – to be installed FREE OF CHARGE along with fresh brake fluid.

The National highway Traffic Safety Administration has issued a formal recall of 210,228 Suzuki GSXRs from model years from 2004 to 2013, citing a brake defect:

According to NHTSA:

Suzuki Motor of America, Inc. (Suzuki) is recalling certain model year 2004-2013 GSX-R600 and GSX-R750, and model year 2005-2013 GSX-R1000 motorcycles. In combination with older brake fluid, corrosion of the brake piston inside of the front brake master cylinder generates gas that may result in a reduction of fluid pressure transmission to the front brake. As a result, front braking power may be reduced increasing the risk of a crash.

Suzuki will notify owners, and dealers will replace the front brake master cylinder, free of charge. The recall is expected to begin on Nov. 4. Suzuki’s campaign numbers for this recall are: 2A (31, 32, 33, 34, 35, and 36).


Call your authorized Suzuki Dealership, provide your motorcycle VIN number and they will order your part.  The motorcycle does not need to be registered (race bikes or track bikes) – the dealership will install the OEM replacement part.


I have spoken to AFM’s Chief Technical Inspector, Terry Cheney – THIS STOCK OEM REPLACEMENT PART WILL BE PRODUCTION CLASS LEGAL.  The change is being instituted as a safety recall and the replacement part will be a stock / OEM part.

“Substitute” parts or non-OEM “in lieu of” parts WILL NOT BE LEGAL for Production class.

I will update with a photo of the new master cylinder when I receive it.
