BRAKE PACKAGES
Your Atom is equipped with one of the following bra ke packages:

Base Floating calipers front & rear with 10.3 in. front v entilated rotor and 10.3 in. rear ventilated rotor.

Sport Wilwood Dynalite 4 piston caliper front and floating PBR caliper rear, with 10.3 in. front
ventilated rotor and 10.3 in. rear ventilated rotor .

Track Wilwood Dynalite 4 piston caliper front & rear calipe r and parking brake caliper with 11 in. front
two-piece ventilated rotor and 11 in. two-piece venti lated rotor.

Race Alcon 4 piston caliper front & rear with 11 in. front two-piece slotted & ventilated rotor, and 11 in.
rear two-piece slotted & ventilated rotor.

Brake pads should be inspected before every track event to ensure that there has been no pad damage,
thickness issues, or deterioration.
The brake rotors should be replaced when their thickn ess decreases to 19mm, when pulsation is noted, or
if cracking or other physical damage is found during in spection. Additionally, the brake pads should be
replaced when replacing the rotors.


Check brake fluid levels often. Some decrease is to be expected as the pads wear. Additionally, the brake
lines should be checked for rubbing or scraping.

PARKING BRAKE ADJUSTMENT


There are two adjustment points on your vehicle’s par king brake assembly, the parking brake actuator and th e
cable slack. Refer to the photos on the following page . To adjust the assembly:

1. Place chocks or blocks in front and in back of the fr ont wheels to prevent the car from rolling.
2. Place the parking brake handle in the forward-most position and put the car in neutral.
3. Jack up the rear of your Atom until the rear whee ls are clear of the ground.
4. Place safety stands under the car.
5. Ensure that the car is stable.
6. Make sure that there is a little slack in the cables where they exit their covers at the rear of the car near
the rear axle.
7. Take a 1/4 in. Allen wrench and turn the internal hex bolt in the center of the large end of the parking
brake application lever clockwise until the wheel cannot be turned by hand. (Track & Race package.)
8. Turn the Allen bolt counter-clockwise about 1/16 of a turn. At this point the parking brake is initialized
and the cables can be adjusted.
9. Loosen the locknut on the cable housings with a 9/16 in. wrench and screw the adjuster barrel counter-
clockwise until there is less than 1/2 in. of vertical sla ck in the cable.
10. Tighten the locknut while holding the cable housi ng stable with a 1/2 in. wrench.

TIRE & WHEEL MAINTENANCE
NOTE: Due to a wide range of driving conditions and techni ques, tire maintenance will vary.
Ariel Atoms are equipped with ultra high performan ce, wet/dry (not all-season) tires. Tire sizes are:
Front 195/50R/15 or 205/50R15 Rear 225/45R16 or 225/45R16
Front tire pressures of 18 PSI, and rear tire pressu res of 20 PSI are the recommended tire pressures for
most applications. Minimum and maximum tire pressures ar e listed on the sidewall of the tires.
Drivers should inspect tires for proper pressure and tre ad wear before every track event. A wide range of
wear patterns are possible due to different driving co nditions.

If you are losing traction it may be time to change t he tires.
Suspension settings may affect tire wear patterns.
Grainy tread may indicate a suspension issue.
Tires may last up to 20,000 miles (32,000 km) under conservative driving conditions or as little as 300
miles (480 km) for track conditions.

The wheels should be re-torqued before every track eve nt. The lug nut torque is 80 ft-lbs.
Most Atoms have different size tires on the front an d the back, and cannot be rotated. If you car’s tires a re
the same size, rotate them every 500-1,000 miles (800- 1600 km). Dismount the tires from the wheels
before rotating them.
