To prevent brakes from overheating while going downhill, you can use engine braking by downshifting to a lower gear, apply brakes intermittently instead of continuously, and avoid riding the brakes for extended periods. This helps distribute the braking force and reduces the risk of overheating.
Your brake might grab when going downhill because the pads are wearing out. The lines may also need bled properly.
Going up hills doesn't allow engine to "lug" and overheat Going down hills supplies engine braking for safety and will prevent brakes from fading and overheating
Yes, it is already in the control system. It has to.
The engine doesn't have to use as much fuel when the car is traveling downhill.
Warped rotor(s), due to too much hard braking (or braking for too long, like when going downhill). You can replace them or get them shaved so they are flat again. Break sooner and not as hard will prevent them from overheating, which causes them to warp.
Most people will tap the brakes of a car when their car is going downhill, usually to keep the car under the speed limit. The squeaking noise could be the brake rotors or the brake pads.Ê
In a downhill area, you should always park with the front wheels toward the curb. The theory is that if the brakes malfunction, the car will move towards the curb and stop, instead of going downhill, gathering speed and causing an accident.
we could go about 35mph when not going downhill you can go 28mph
Typically these lower "gears" are used for towing to keep the engine within a certain power band for towing (so it doesn't shift up a gear and lose power by going out of the power range at a lower rpm). Also, you should be shifting into a lower gear, say from "D" to 3 or 2 if you are riding significant downhill roads where you take advantage of engine braking and so do not have to ride the brakes and run the risk of potentially overheating your brakes (hot brakes become less effective).
When engine brakes are restricted, it means that the vehicle's braking system that uses the engine to slow down is limited or not functioning properly. This can affect the vehicle's ability to slow down efficiently and safely, especially when going downhill or carrying heavy loads.
Rotors warp when they overheat. Perhaps you're riding the brakes, have a sticking caliper or are going downhill a lot and are overheating the brakes that way. Often pulling a trailer will overheat the brakes, especially if the trailer does not have electric brakes. If none of the above seem to apply to your situation, perhaps someone put cheaper rotors on the vehicle; some of the import rotors look the same but they warp quite easily. Also not torquing the lug nuts correctly can warp the rotors. If the lug nuts are put on too tight the rotors will warp on some vehicles.
No the can go faster downhill or uphill
