Triumph TR4/4A/5/250 Front BrakesEarly TR4s had different calipers and brake discs to later TR4's due to alternate caliper mountings on the vertical link and slightly larger discs.
- TR4 (Early up to comm no. CT4689 (Wire Wheels), CT4387 (Steel wheels).
- TR4 (Late) from above Nos onwards (January 1962 approximately).
The later TR4/4A/5/250 used the same calipers adn discs, being common with the early TR6 (although 2 different caliper seal kits ere used).
Please note that the later TR6 had metric calipers dn whilst they will fit all but early TR4's (if fitted unknowingly by a previous owner), it should be noted that metric pipes, bolts and different pads are required.
