It's PROBABLY warped disk brake rotors. Brake rotors will warp when overheated and if you go downhill very often, they've probably overheated.
Replace the rotors with a high quality product and they'll last longer.
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.
it shakes to the right or left
usually steering shakes over 60 mph is due to front tires needing to be balanced unless you have something more serious going on.
Braking distance may increase when going downhill because gravity is working against the brake system, causing the vehicle to maintain momentum. The added force of gravity can make it more difficult for the brakes to slow down the vehicle quickly. Drivers should use caution and brake at a safe distance to account for the increased braking distance.
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.
You may have a ball joint going out or your wheels are unbalanced
If the brake is applied strongly while going downhill, it can lead to a loss of traction, causing the wheels to lock up. This can result in skidding, making it difficult for the driver to maintain control of the vehicle. Additionally, excessive braking can cause brake overheating, leading to brake fade, where the braking efficiency decreases. Ultimately, this could increase the risk of an accident.
check the balancing on the tires.
we could go about 35mph when not going downhill you can go 28mph
Have your tires rotated and balanced. Make sure they inspect the tires/wheels for any damage.
Milk Shakes! They are always going to the resturaunt to have milk shakes.
No the can go faster downhill or uphill
