AP Racing APF401 Guía De Instrucciones página 2

• AP Racing Offer a number of Pad materials suitable for different uses:
• APF401 - Competition Pad suitable for Circuit & Rally use. Good bite and stable friction give excellent modulation & release characteristics
• APF402 - Competition Pad for Circuit & Rally use. Not suitable for road use. Higher friction than 401, rising torque, good release , little or no fade.
• APF403 - General Competition Pad. Not suitable for road use. Easy to bed, predictable and repeatable performance with good bite & friction.
• APF404 - Excellent High Performance Road and Track pad. Consistent performance, low wear, disc friendly, low noise, low dust, low fade, good feel.
• APF405 - Suitable for High Performance Road, Track and Lightweight circuit cars.
• APF406 - Competition Pad. Not suitable for road use. Low wear, predictable performance.
N.B. The above information is offered for guidance only. Not all materials are available in all pad shapes – AP Racing have chosen the most suitable materials
to match the predominant applications for each pad shape.
Proceed with caution, Do not use brake system heavily until the following
To achieve optimum performance from any brake pad it is essential to bed them in properly, AP Racing brake pads are no different in this respect. The aim
of the bedding procedure is to achieve 100% mating of the friction surfaces and thermally condition both Disc and Pad by gradually increasing temperature
without creating any thermal shock or hot spots. A small investment of time to follow the recommended bedding procedure will enhance performance and
improve the life of both Pads and Discs. Please follow the procedure below:
(a) For Racing use:
1) While vehicle is stationary, pump brakes to bring pads into contact with the disc and ensure a fi rm pedal.
2) Use Light braking for 2 or 3 laps (5 Km) using 50% of normal race pedal pressure to obtain full (over 80%) contact between Disc & pad. Do not drag the
brakes against the engine.
3) Gradually increase speed and braking pressure for another 2 or 3 laps until full racing speeds are reached to progressively build up temperature in the
Discs & Pads.
4) Cool the brakes by driving the vehicle for another lap with minimal brake use and then return to the pits. Allow the brakes to cool. The pads should now be
ready to race.
N.B. (1) If time permits it is recommended that the pads are removed and inspected after bedding. The full surface of the pad should show
evidence of contact with the disc but without glazing. If this has not been achieved further bedding applications should be carried out.
(2) If possible avoid bedding new Pads on new unbedded discs, use a previously bedded/used Disc which has a smooth fl at friction
surface.
THERMAL PAINTS: It is helpful during bedding and racing to check maximum Disc temperatures using thermal paints (e.g. AP Racing Kit CP2649-1)
to ensure that the optimum temperatures are being achieved. Where the above bedding procedure has been carried out and braking performance is not
considered satisfactory, if the green paint has not changed colour it may be necessary to reduce cooling to the discs, if the red paint has changed colour it may
be necessary to increase cooling to the discs.
(b) For Road & Track day use:
1) While vehicle is stationary, pump brakes to bring pads into contact with the disc and ensure a fi rm pedal.
2) Drive vehicle cautiously to test fi t and function. Brakes should be smooth, with no vibrations, judder, excessive noise etc.
3) Drive the vehicle to a remote area and carry out at least 30 light brake applications from 55 mph to 30 mph, preferably in blocks of 5. Leave at least 1/2 mile
between each block of 5 brake applications
4) For the next 100 miles, increase the braking pressures, avoiding if possible full stops from over 70 mph. After another 100 miles of progressively increasing
the braking effort, full power stops can be used. .
5) The system is now ready for normal use.
PAD WEAR INSPECTION: Brake pads should be regularly inspected for wear. Brake pads must have at least 2mm of friction material above the
metal backing plate and be reasonably fl at. Excessively worn brake pads must be replaced.
