Bonaldi Brake Pressure Control Valve Seal Kit


A Muscle Car Research Exclusive!

Muscle Car Research is proud to offer a rebuild seal kit  for the Bonaldi brake pressure control valve used on the 1971 - 1974 de Tomaso Pantera and 1973 - 1979 Lamborghini Urraco. Our kit contains all of the internal parts needed to rebuild your leaky valve and return it to "like new" operating condition, including:

  • Large Sealing Washer
  • Small Sealing Washer
  • Copper Sealing Washer

The kit does not currently include an external rubber dust cap. I'll look into adding this part to the kit if there's enough demand.

All of the parts are molded from a 70 durometer ethylene propylene diene monomer (EPDM) rubber compound that is fully compatible with automobile brake fluid. The rubber sealing washers are custom made right here in the USA, and the copper sealing washer is made in Germany.

According to my parts catalogs original applications include the following vehicles:

  • 1971 - 1974 de Tomaso Pantera (D16Y-2B091-A (early) and D26Y-2B091-A (late))
  • 1972 - 1979 Lamborghini Urraco P111, P200, P250, and P300

Complete rebuild instructions are available from the Muscle Car Research web site. Dealer inquiries are welcome - please contact us for pricing.
