Brake Maintenance
3. Your brake system should be overhauled every 6 months. The system should be stripped, washed
in water or methylated spirits, new seals fitted and re-bled. Your kart dealer can overhaul your
brake if you are unable. “Don’t wait for a failure – preventative maintenance is much wiser.”
4. Arrow karts are supplied with brake pads developed over 2 years of extensive testing. Don’t
use substitutes as they could affect your brake disc and result in poor braking performance.
The correct part no. is BDHL7 or BDHL 5.
5. When your kart is new or whenever you fit new brake pads ensure you follow this “bedding-
in” procedure. Correct bedding-in improves pad life and braking performance.
Session 1: For approximately 10 laps lightly apply brakes only, gradually increasing pressure used to
approximately 40% of full braking.
Session 2:
For the next 10 laps gradually, lap by lap, increase pedal pressure so that braking is occurring
at approximately 75% of full braking by lap 20.
Session 3: Do 2 laps at approximately 75% full braking and then for the next 2 laps work the brake
hard. Ride the brakes then let off the pedal for 2 seconds and ride them again. Continue this until the
brakes become very hot and they start to fade away and lose stopping power. For the next 2 laps drive
around very slowly and do not even touch the pedal, allowing the brakes to cool down, return to the
pits and allow the brake to cool down completely before returning to the track.
Note: For a new kart or new brake disc, complete sessions 1,2 & 3.
For new pads only, complete just session 3.
Fitting Tyres
Fitting tyres will depend upon the class the kart is being assembled for. When inflating the tyre to seat the
bead, do not over inflate. There is a very real risk of serious injury if the manufacturers advice printed on
the sidewall of all tyres is not followed. To aid the seating of the bead a light coating of soap applied before
inflation and using external steel tyre rings around the tyre will help. Do ensure all tyres are wiped after this
process and check for any damage or defects before placing the tyre on the kart.
Note: Using the Kartech Adjustable external steel tyre ring is important as a safety issue as well as
performance as they reduce the amount of pressure required to seat the tyre’s bead onto the
rim. Apart from the obvious safety advantage, this does stop the tyre from being stretched out of
circumference or shape.
