Solution Solves Parking Break Noise Issue
Premium Car Maker Eliminates NoiseIssue with High-Performance Lubricant
A premium European motor manufacturer witha famous sporting pedigree needed to eliminate
a persistent and annoying noise issue found in theparking brake mechanism that had been supplied
by a key partner.

The ChallengeThis example of "buzz, squeak and rattle" was notconsistent with the brand values and aspirations ofthe vehicle manufacturer. It was, therefore, essential
to improve the in-cabin experience for the end user
by eliminating the problem. An easy to apply, costeffective and life-long lubrication solution was neededthat worked where multiple components made fromdifferent materials were coming into contact.

Performance Lubricants

The Solution
Our automotive experts, working with the manufacturer’s
design engineers, identified that the noise was originatingwhere contact was occurring between the seal and the metal
piston rod in the brake actuator mechanism.
We suggested the application of Krytox™ GPL 205 grease toact as a PFPE film on the seals, which would ensurecomponents worked together without friction. As soon as thiswas done, the noise was eliminated. Further life testing
confirmed that the solution was effective.
