RECALL NO. 20E042 – JUNE 2020

 

To: Raybestos US Customers

Re:  Recall of Certain Raybestos New Master Cylinders (Part # MC391232)

 

Dear Valued Customer:

We are writing to inform you that Brake Parts Inc LLC (BPI) is conducting a voluntary safety recall of certain New Master Cylinders, Part No. MC391232, intended for aftermarket installation on the passenger vehicles listed below. Our records indicate that products covered by this recall may have been shipped to you.

August 2020

 

Dear NAPA Customer:

This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.  Our supplier, Brake Parts Inc., has decided that a defect which relates to motor vehicle safety exists in certain NAPA-brand aftermarket brake master cylinders, Part No. M4840, manufactured 01/01/2016 through 04/27/2020.

We are notifying you because our records indicate that you may have purchased one of these products. Therefore, please review this letter carefully.

 

What is the Problem?

The crimping of the aluminum housing may be insufficient, which, in extreme cases, may allow the master cylinder piston to pop out of the housing early in its service life. If the piston pops out of the master cylinder housing, a complete loss of braking or unintended brake application can occur, increasing the risk of a vehicle crash. Prior to total failure, the vehicle operator may experience some loss of braking power due to brake fluid leaking past the primary piston and damaging the vacuum booster.

To confirm that your master cylinder is covered by this recall, you will be asked to provide a copy of the receipt or invoice that includes the dealer/installer name, location, and date of purchase.  The dealer/installer will order a replacement part and notify you when it is available for installation. A replacement will be provided free of charge (parts and labor).  The repair should take approximately two hours to perform, but due to scheduling, the dealer/installer may require your vehicle for a longer period of time.

If your NAPA M4840 master cylinder has not yet been installed, please return it to your NAPA dealer for a refund.

If you no longer own the vehicle on which this product has been installed, please forward this notice to the new owner and provide the new owner’s address to Mr. Doug Harmon, Brake Parts Inc., at 1-800-323-0354 or bpi.claims@brakepartsinc.com.
