Description Technical Specs

Product description

Our newly upgraded Powerbrake AT-Series High-Carbon slotted discs are unmatched in terms of performance and durability. These discs are direct replacements for the original discs on your 4x4 or SUV and require no modifications to the vehicle at all for fitment. Cast from a new High-Carbon cast iron alloy that increases the thermal conductivity of the material resulting in a reduction of thermally induced stresses in the disc during operation. The end result is an extremely stable disc casting that is more resistant to distortion (warping) or cracking than original equipment or standard aftermarket discs. The dry coating on our upgraded AT-Series discs has been changed from the silver coating (used previously) to the same black coating that we use on our 2-piece floating discs in our big brake kits and race brake systems. The black coating can handle higher temperatures and will provide improved corrosion resistance. Our AT-Series discs are machined to extremely tight tolerances (up to three times tighter than the industry norm). Every single disc is measured for runout and disc thickness variation (DTV) using state-of-the-art measuring equipment. We will not ship a disc with a run out value greater than 0.03mm or a DTV value greater than 0.005mm. This 100% measuring policy is very rare in the industry and ensures that every disc we ship is perfect in terms of dimensional accuracy when it leaves our factory. The slot pattern employed on our AT discs delivers the optimum balance of initial bite, quiet operation, fade resistance and best-in-class mud / sand / water clearance. In addition to being used by many thousands of 4x4 and SUV owners in both on-road and off-road driving conditions with excellent results, our AT-Series slotted discs have also been used very successfully in off-road race series such as the Donaldson Cross Country Off-road Championship. The new Powerbrake AT-Series High-Carbon discs set the benchmark in high-performance, slotted brake discs for 4x4 vehicles.

Recommended brake pads

The high performance pad compounds below have been extensively tested by Powerbrake to offer the maximum brake upgrade when used with our AT Series high-performance slotted discs. These pad compounds can be viewed and/or ordered by returning to the previous page and selecting the relevant pad compound from there.
  • Bendix Ultimate brake pads: A true upgrade pad compound offering significantly upgraded stopping power, fade resistance and wear life over factory and most aftermarket pads.
  • Powerbrake PB05 brake pads: Unmatched in terms of brake performance, fade resistance and pad life. A further step up over Bendix Ultimate pads. This is the highest level upgrade pad for 4x4's / SUV's on the world market at the moment in our opinion.

5 of 5 Hilux Powerbrake August 6, 2018
Reviewer: Jaco Dippenaar from JHB, GP South Africa  
I fitted the discs and brakes as per very clear instructions provided. Very satisfied with the results. Brakes are a lot more powerful than OEM Hilux brakes.

5 of 5 Discs April 19, 2017
Reviewer: Barry Revell from Dundee, KZN South Africa  
Fitted the discs - no hassels - 47000km on the first set and now these - The vehicle (Toyota Hilux 4x4 V64l) is used mostly for holiday trips and tows an unbraked off road trailer most of the time, so more brake power is required - I found the first set were a big improvement on the standard brakes. The obvious choice when they wore out was get some more.
