Follow the instructions below for bedding in your Performance Friction pads
  1. Tape up ducts ½ - ¾. Make several slow stops to ensure sufficient pad/disc contact area (typically 80%).
  2. Do not left foot brake. Do not drag brakes. Make several firm/hard stops from as high a speed as possible. These stops should be made early, as all pads will exhibit fade until fully conditioned. On light braking circuits extra stops on long straights can be made to speed bedding process. Continue procedure until fade is no longer apparent.
  3. Important - make 1 or 2 cooling laps without using brakes.
  4. Check temperature paints - discs must have reached peak operating temperatures to be sure of full bedding. Remove tape as required.
When bedding in the car always try to bed on used rotors. If bedding on new rotors follow the rotor bedding instructions of the manufacturer, as it is important to heat cycle them first before bedding the pads. After fitting the new pads prepare the car by blocking off 50 percent of the brake cooling / air ducts to speed the “heat up time”. When leaving the pit lane apply brake gently at low speed to ensure pads are fitted correctly, build up temperature progressively to approx 350° C (670° F). This enables the heat to distribute around all areas of the pad.

When brakes are at suitable temperature begin bedding process, achieve approximately 70 percent of race speed then perform 25-30 brake applications at half normal race pedal pressure holding on for 4 seconds.
When this is completed use a slowing down lap to allow brakes to cool. Return to the pit lane and allow pads to cool completely, check rotor appearance. Transfer film should be constant around rotor face, any “patchy” deposit will result in brake pedal judder. The use of temperature paint on rotors enables more accurate bedding procedures.

Follow the supplied bedding guidelines and not bedding procedures based on old technology. Failure to do so could result in brake components overheating and possible failure. Bedding Mintex F-Series material requires 12-24 short hard stops while gradually building temperature. To do this without overtaxing the system, the stops should be done in low gear to ensure that the energy input is limited. Accelerate to a high RPM level and apply the brakes in a short hard snub. Once a pre-determined lower RPM level is reached the driver should accelerate back to the high RPM immediately and repeat the procedure a further 8-10 times.

After this a lap can be driven to test the brakes. If necessary the entire process can be repeated to give a better feel. On returning to the pits the brakes should be allowed time to cool and the system bled before further use. It is stressed that when carrying out the bedding process, the brakes are not dragged or the car taken from very high speed to very low or a stop. To do so many results in damage to or failure of brake system.

M1144 /  M1155 /  M1166 /  M1177

1. Clean discs with brake cleaner or other solvent.
2.  Apply  3 to 4 light applications of the brake from 30mph down to 0mph
M1144:    6 / 7  steady applications 70mph down to 30mph
M1155:    8 / 9  steady applications 90mph down to 30mph
M1166:    9 / 10  steady applications 90mph down to 30mph
M1177:    9 / 10  steady applications 90mph down to 30mph

FINALLY....  Leave to cool as long as possible ( They now work from cold )
Geometric Alignment Of Pad Surface To Disc Surface (basic bedding in)

4-6 brake applications with medium pedal pressure from approx 90mph to 50mph, not allowing wheels to lock. (No brake dragging)

Allow for a distance of 300 - 400metres between brake applications for cooling period.

Pads should not reach temperatures above 400°C during initial bedding in. Check that pad surfaces have at least 80% contact with disc before allowing more heat into pad surface.

Immediately followed by :
  • Bedding In At High Speed  
  • 1 brake application with medium to high pedal pressure from approx 110mph to 50mph without allowing wheels to lock.  
  • Allow 3-4 recovery brake applications with light pedal pressure.

Repeat high speed applications including recovery applications another 2-3 times.

NOTE: Allow a cooling off distance of 500 metres between high speed application
