Race Car Solution Makes Your Street Car 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 pushing the pistons back into the bores in the brake calipers.
Once the pistons have been pushed back, it takes a whole master cylinder full of
brake fluid to get them back out again, and the pedal goes to the floor. Then, the
second pump slows the car. But what if you don't have time to pump twice?!
The problem described above was solved on BMC cars, MGB, Austin-Healey,
etc., at the factory by fitting spacers between the front wheel bearings, but Triumph
engineers didn't recognize that there was a problem. The bearing spacers listed
here use the BMC way of thinking to improve Triumph models. In addition to the
spacers which fit the stock front axles, there is a wonderful kit which includes
bigger, stronger stub axles along with the spacers.
