RDA Brakes have been supplying Australia with bonded shoes since 1998
RDA brakes shoes carries the brake lining, which is glued/bonded to the brake shoe.
When the brake is applied, the shoe moves and presses the lining against the inside of the drum.
The friction between lining and drum provides the braking effect.
Energy is dissipated as heat.
Excessive heating can occur due to heavy or repeated braking which can cause the drum to distort, leading to vibration under braking.
Excessive heating of the brake drums can cause the brake fluid to vaporise, which reduses the hydraulic pressure being applied to the brake shoes.
Therefore less retardation is achieved for a given amount of pressure on the pedal.
The effect is worsened by poor maintenance.
If the brake fluid is old and has absorbed moisture it thus has a lower boiling point and brake fade occurs sooner.
Brake fade is not always due to the effects of overheating.
If water gets between the friction surfaces and the drum it acts as a lubricant and reduses braking efficiency.
The water tends to stay there until it is heated sufficiently to vaporise, at which point braking efficiency is fully restored.
IMPORTANT CHECK POINTS
Avoid high speed braking or excessive braking until new brake drums and brake shoes are "bedded-in" to avoid overheating and subsequent reduction in braking performance.
A distance of at least 200-300 kms is recommended for a running in period.
All RDA quality brakes shoes are covered by the RDA 12 month 20,000 km warranty.
Every set of RDA bonded shoes is boxed for easy storage, and to reduce the possibility of damage to the friction material in transit.
The RDA shoe range has been specially formulated to ensure low noise, low dust and maximum stopping power.
Our wide range covers everything from Alfa to Volvo, including the older vehicles dating back the 1950s.
