HYDRAULIC BRAKE SYSTEM
WARNING
When working with the disc brake, observe the precautions listed below:
1.
Disc brakes should only be installed and serviced by someone competent in the installation and maintenance of disc
brakes. If you have any questions, contact customer service at 1-800-854-3140.
2.
Never reuse old brake
fl
uid.
3.
Do not use
fl
uid from a container that has been left unsealed, or that has been open for a long time. Brake
fl
uid draws
moisture when exposed to air.
4.
Do not mix two types of
fl
uid for use in the brake; this lowers the brake
fl
uid boiling point.
5.
To avoid moisture contamination of the
fl
uid, do not leave the reservoir cap o
ff
for any length of time.
6.
Don't change the
fl
uid in the rain, or when a strong wind is blowing.
7.
Except for the disc pads and disc, use only brake
fl
uid, isopropyl alcohol, or ethyl alcohol for cleaning brake parts.
Do not use any other
fl
uid for cleaning these parts. Gasoline, engine oil or any other petroleum distillate will cause
deterioration of rubber parts. Oil spilled on any part will be di
ffi
cult to wash o
ff
completely, and will eventually
deteriorate the rubber used in the disc brake.
8.
When handling the disc pads or disc, be careful that no brake
fl
uid or oil gets on them. Clean o
ff
any
fl
uid or oil that
inadvertently gets on the pads or disc with “Brake Kleen” or other suitable cleaner. Do not use cleaners that will leave
an oily residue. Replace pads with new ones if they cannot be cleaned satisfactorily.
9.
Brake
fl
uid quickly ruins painted surfaces; any spilled
fl
uid should be wiped up immediately.
10.
If any brake line
fi
ttings or bleed valves are opened at any time, THE AIR MUST BE BLED FROM
THE BRAKE SYSTEM.
NOTE:
Brake
fl
uid quickly ruins painted surfaces; any spilled
fl
uid should be wiped up immediately. Brake
fl
uid is water-soluble;
use wet rags to clean up brake
fl
uid.
BRAKE HOSE
When removing the brake hose, temporarily secure the end of the brake hose to a high place to keep
fl
uid loss to a mini-
mum. Make sure not to spill brake
fl
uid onto painted parts. Use wet rags to clean up any spillage. Bleed the brake line
after installing a brake hose.
BRAKE HOSE INSPECTION
High pressure inside the brake line can cause
fl
uid to leak or the hose to burst if the line is not properly maintained. Bend
and twist the line while examining it; replace it if any cracks or bulges are noticed.
DISC INSPECTION
Visually inspect the brake disc. If grooved or worn, replace the brake disc. Original disc thickness is .250”. Minimum disc
thickness is limited to .235”. Place a stand or block under the go-kart so that the rear wheel is raised o
ff
the ground. Set up
a dial gauge against the disc; rotate the wheel to measure the disc run-out. The di
ff
erence between the highest and low-
est dial readings is the amount of run-out. If the disc run-out exceeds the service limit, replace the disc.
