The Girling name is a legacy brand that dates back to the 1920s and has long been known for innovation and quality brake parts. A completely new lineup of motorcycle brake components is now available replicating the original equipment as specified for BSA, Norton, and Triumph motorcycles.
The front brake master cylinder service kit comes with all the internal parts to rebuild the Lockheed master cylinder barrel, as specified on Triumph disc brake models. Included also are the o-ring for the reservoir cup and the diaphragm. Top quality Girling kit made in the UK.
The succession of the piston and primary and secondary cups in the assembly allows the flow of hydraulic fluid to pressurize and release within the bore of the master cylinder. The bore must be smooth and free of corrosion and pitting to optimize performance and safety.
The system must be drained of hydraulic fluid and the master cylinder components withdrawn from the master cylinder bore. Cleaning and inspection of the bore must be performed before reassembly according to the instructions in the workshop manual.
