EBC Brake pad comparison & comments used for North Island Endurance Series 2011
Our car is BMW 318is, producing approx 130whp. Utilizes BMW 325i calipers, vented discs and single pot calipers.
FRONT
YELLOW
Used for 6 Hour Endurance at Pukekohe May 2011, including Friday practice and
set up as well as qualifying, total of approx 7 hours of track time.
Weather was fine and dry.
New: friction material is 11.4mm ( excluding backing plate)
After 7 hours friction material ranged between 8.1 and 8.9mm (average 8.44mm)
a use of 2.96mm. Pad wear was fairly even accross the leading and trailing edges.
Pukekohe of course is a circuit which is not heavy on brakes and only two applications
per lap. Yellow is our normal choice of pad both back and front for both sprint and
endurance racing. We like it and have used it for years.
FRONT
BLUE
Used for 4 Hour Endurance at Taupo, June 2011, including Friday practice and
set up as well as qualifying, total of approx 5 hours of track time.
Weather was wet and cold. Approx 2.0 hours on a dry track and the balance wet.
New: friction material is 11.4mm ( excluding backing plate)
After 5 hours friction material ranged between 9.7 and 10.25mm (average 10.1mm)
a use of 1.03mm.
Taupo is a circuit of hard braking, with approx 6 applications per lap.
Interesting that the leading edge of each pad wore approx 0.5mm more than the
trailing edge. Pad measurement (which we had not carried out on yellow pads):-
LH Inner leading edge 10.25mm - RH inner leading edge 9.93mm
LH Inner trailing edge 9.75mm - RH inner trailing edge 10.65mm
LH outer leading edge 10.25mm - RH outer leading edge 9.7mm
LH outer trailing edge 9.65mm - RH outer trailing edge 10.7mm
REAR
YELLOW
Both events used approx 3/4 of the pad friction pad material
OUR OPINION
Bluestuff NDX brake pads gave as good cold bite as
Yellowstuff brake pads,
however the pad gave much more feel back through the brake pedal. The pad almost
seemed less harsh than yellow, but gave a more confident feel, and also felt like
increased control through the pedal. Really like the
Bluestuff NDX brake pads and
would like to continue use for the new season sprint races.
All pads retained their integrety and show no signs of any crumbling on edges such
as many pads do. Including to a small degree the
Yellowstuff brake pads.
