Pads characteristics thread


descrierea capului de tabel:

? Average friction: Overall mean friction coefficient calculated over the complete test cycle. (Fig 1.)

"Bite": Initial friction at the start of the stop. 
Rating 1 to 5. (5 = Good, 1 = Poor) (Fig 1.)

Fade: Drop off in friction coefficient from stop to stop when used for very hard braking. Calculated from last 4 stops on test plot on a scale of 1 to 5. (5 = No significant fade). (Fig 1.)

Average pad wear: A comparative rating of pad wear across all conditions.Rated on a scale of 1 to 5 ( 1 = best).

Plot Shape: The shape of the friction plot during a brake 
application. High initial "bite" with friction gradually decreasing through the stop as speed drops off is considered to be the easiest to control (most "user friendly"). A climbing friction level through the stop is considered the most difficult to control (least "user friendly") although some pads with this characteristic are extremely popular due to their overall high friction level and fade resistance. Assessed types 5 to 1. (Fig 2.)

Comfort / Noise: Does the pad promote judder or brake squeal ?. Important on road car applications but not usually a 
consideration for racing use.

Disc Life: Does the pad promote high disc wear or cracking?. Especially important on road car applications. 
Rated on a scale of 1 to 5 ( 5 = best).

Effective Temperature Range: The temperature range within which the pad material can be considered effective should be used as a comparative guide only as temperature measurement techniques vary significantly and the true picture must include the energy level (quantity of heat). Pad temperatures are affected by disc mass and cooling. 
Rated 1 to 5 (1 = 200°C / 2 = 350°C / 3 = 500°C / 4 = 650°C and 5 = 800°C).

Suitable Area of Use: The areas for which the pad material is considered most suitable. This is a subjective assessment 
relying on the pooled experience of AP Racing engineers over many years. Contact AP Racing Technical Section for guidance.

Pad Material Performance: The table below provides the ratings given for the characteristics described on the this page. The table results are AP Racing’s own, determined from our dynamometer testing and may differ from manufacturers own specifications.

Y denotes suitable, X denotes not suitable
