ADJUSTABLE BRAKE BALANCE BAR
(as fitted on kart models with front brakes)
PROBLEM: “Too much front end bite on turn-in” (steering wheel tries to rip from your hands)
Solution: On karts fitted with front brakes, adjust the brake bias to increase rear braking.
The brake balance bar on karts with front brakes allows you to regulate the percentage of braking done
between the front and rear wheels. The balance bar distributes the brake pedal movement transmitted
to the front brake’s and the rear brake’s master cylinder pumps. The first way of adjusting the brake bias
is to do it when the kart is on the kart stand. Adjust the brake balance bar into a position where, with
pressure applied on the brake pedal, both front and rear wheels can just be turned by hand.
NOTE: We recommend turning the knob right in and then back out six whole turns.
BRAKE MAINTENANCE
1. On Arrow karts fitted with nylon hydraulic brake lines, always check that the spring nut brake
line protection fitting is done up tight.
These Spring nuts are fitted at both ends of each
brake line to help protect the tubing from accidental
crimping. To do their job properly they must always
be done up tight. It is therefore essential that they
are checked each day before using your Arrow.
They have left hand threads so must be turned anti-
clockwise to be tightened.
2. Always check the feel of the brake pedal making
sure it feels hard without any sponginess.
If the pedal does feel a little spongy, bleed the system only using racing Dot-4 grade hydraulic brake
fluid. Before attempting to bleed the brake, retract the dust boot on master cylinder to check if the
piston is against the circlip (adjust the pushrod if necessary). To bleed the brake, depress master
cylinder lever. Whilst keeping pressure on the lever, open the bleed screw in the brake caliper. Keep
pressure on the master cylinder lever until the bleed screw is tightened. Release the lever. Repeat this
process while maintaining the reservoir fluid level, until the new fluid has been flushed through the
system. Repeat for other side of the caliper. If, having done this, the brake pedal still feels spongy,
check for leaks. As a safety check, make sure the pad retaining bolts are tight. We do check them at
the factory but double-checking never hurt anyone. Not checking might!
NOTE: Do not use Silicon brake fluid!
