"Race Car Solution Helps Your Street Car to Stop Better"
Triumph racers have long suffered from a baffling
brake problem. Their cars might be in perfect
condition with great brakes, but when they are driving
very hard, particularly on rough surfaces, the brake
pedal sometimes goes right to the floor when they
really need to slow down. The reason for this problem
has been diagnosed, and a cure has been found.
Triumph front stub axles are a bit flimsy. If you don't believe me, remove one of
your front hubs, and then you will see what I mean. Picture these axles when the car is
running at speed on curvy roads, especially ones with rough surfaces. Those little axles
flex like crazy under such conditions. When the axles flex, the brake discs wobble
around between the two sides of the brake calipers, pushing the caliper pistons back into
their bores. Once the pistons have been pushed back into their bores, it takes a whole
master cylinder full of hydraulic fluid to get them back out again, and the pedal goes to
the floor. Then, a second pump slows the car. But, what if you don't have time to
pump twice?
The problem was solved on BMC cars—BMC made MG, Austin-Healey, etc.—at
the factory by fitting spacers between the inner and outer front wheel bearings to stiffen
the stub axles, but the Triumph factory just didn't address this problem. A few years
ago, the problem was addressed, however, by Jack Drews, a Triumph race parts supplier
who has now passed away. Jack Drews offered spacer kits to solve the Triumph
problem in the same way that it was solved on BMC cars. He also produces a
wonderful kit which includes heavier, stronger stub axles along with spacers. It is
interesting that Jack Drews originally thought there might be a market for only about
fifty of his axle and spacer kits. TRF has now sold about two-hundred, and we continue
to purchase the kits from Jack's son, Tony.
