Triumph TR6 Girling Type 16PB Brake Calipers from Comm nos CP26076 to CP76094 & CC29929 to CC81078 - Imperial Threads
The repair kits and pistons for early calipers with imperial thread can be of two types and they are not interchangeable. The later type kit (part no. 519731) differs from the early kit (part no. 601960) in using a steel clip to retain the dust shield on the caliper body. For further reference please refer to the illustrations.
The calipers 307977 and 307976 can be replaced directly by either the later imperial threaded items or by the metric threaded ones if the appropriate brake pipe and caliper mounting bolts are used.
From commission nos. CO26076 to CP76094 and CC29929 to CC81078. Imperial threads.
