Good day to everyone,
I have started to ride the 1995 Triumph Thunderbird more often since I raised the seat somewhat using a AirHawk whoppy cushion that seems to work. But I have noticed that the front brake fades if hard front braking is applied. My question for the group has anyone upgraded their front caliper from a two (2) piston To a four (4) piston caliper and what success did you have?

Hello B25bsaboy , is the bike still fitted with the standard front brake hose ? If so i think its well documented that they were never the best and could expand slightly when getting on in years , Perhaps a new braided hose and thorough bleed through may be easier than modifying the caliper with the same or better end result

The older rubber brake line was changed, mater cylinder rebuilt and brake caliper rebuilt. I think the biggest issue is the the mater cylinder internal diameter needs to be increased in size! Just a thought, as I did this to a 1976BMW R75/6 and it greatly improved the braking powe.

If you can find the front left hand caliper from a CB1000R with ABS, it is a straight bolt on. It’s a three pot set up.

The Nissin 3 piston and later 2 piston sliding calipers fit, try your local breaker, CBF600/1000 models and others. 4 piston units don't fit as the inner piston area fowls the spoked wheels. Before buying though do the usual, service the caliper with new seals new fluid and same for master cylinder. should have braides hoses as standard, maybe good quality new pads may help.
