A retarder brake, commonly used in heavy vehicles, functions by using hydraulic or electric systems to create resistance against the vehicle's wheels, thereby slowing it down without relying solely on traditional friction brakes. It operates by converting the vehicle's kinetic energy into heat, which is dissipated, helping to maintain speed control on downhill grades and reduce brake wear. This system enhances safety and efficiency, particularly in long-haul driving situations. Retarders can be especially effective in managing heavy loads while preserving the primary braking system for emergency situations.
Are you talking about the Jake Brake on semis?
Usually busses do not have retarders because they are too loud and cannot be used inside most city limits on a semi truck they have a switch to turn on the jake brake (engine brake, or retarder) when the switch is on and you let the accelerator all the way up the brake takes over. All a retarder does is use your air brakes (or hydraulic) less to prevent overheating that will lead to brake loss.
Steep downgrades, when you need it to control your descent.
a retarder shouldn't be using an automobile in the first place
no it do not answer my question
No, you should not turn off the retarder when the road is wet or snow covered because the retarder helps to slow down the vehicle without relying solely on the brakes. Keeping the retarder on can help maintain control and stability in slippery conditions.
If none of the brake lights are working i would suspect the brake switch at the brake pedal.
No
the brake light driver side not working
probably the brake light switch on the pedal if none are working at all
fsa
It slows down the drying time
