Powerbrake PB62I rally raid calipers are used by three cars in the top 11 at the 2012 Dakar rally
What a great result for the Imperial Toyota / Hallspeed / Overdrive team, with 3rd (Giniel De Villiers), 6th (Lucio Alvarez) and 11th (Duncan Vos) place finishes for their South African built Hilux race cars!
Bear in mind that the Hilux's were built to 2013 specifications, with production engines that produce significantly less power and torque than the MINI's and Hummer's that they were competing head-on-head with. It is interesting to note that if you only look at cars that were built to the 2013 specs, the SA built Toyota's would have finished in 1st, 2nd and 3rd place. Interesting food for thought....
The Hilux's proved to be extremely tough and reliable throughout the 2012 event, which saw almost 50% of the cars withdraw due to mechanical failures and accidents. This is a testimony to Glyn Hall and his entire team at Hallspeed / Toyota Motorsport SA, who are responsible for the development and manufacture of the cars in their state-of-the-art facility in Kyalami, South Africa.
The Toyota Hilux's ran Powerbrake PB62I 6-piston rally-raid calipers and 320x32mm semi-floating GT-Series race discs. The calipers are CNC are designed and manufactured from solid billet aerospace grade aluminium at our factory outside Pretoria, South Africa. The PB62I caliper design includes internal fluid crossovers and 'hidden' bleed screws, as traditional external crossover tubes & bleed screws would be destroyed by the stones, rocks etc encountered under rally-raid conditions.
The calipers also feature heavy-duty, thick-wall stainless steel pistons and ultra high-temperature pressure seals. Our unique internal wiper seal design effectively protects the pressure seals from sand and debris without the negatives associated with external dust boots, as used by many of our competitors. Powerbrake also employs a proprietary design that limits piston knockback (often encountered when racing on rough, corrugated surfaces) without the use of anti-knockback springs.
The team reports that the brake performance was "excellent" with the brakes offering very strong performance and faultless durability throughout the event, which consisted of almost 9000 km’s of racing over some of the harshest terrain on the planet. One of the team’s cars completed the entire event on a single set of Powerbrake GT-series race discs. This is an outstanding achievement considering operating temperatures ranging from -5 to 45 deg C and countless water crossing (which are extremely hard on hot brake discs).
We are very proud of the way our brake calipers and discs performed during the 2012 Dakar. Performance and durability have been hallmarks of Powerbrake race brake components from the outset and we can think of no better proving ground of this philosophy than the Dakar, who many call "The toughest race on earth".
