brake pad loose in caliper, replace fitting kit, check for missing spring shim.
not usually. warped rotors will cause a vibration during braking.
What percent of braking are front wheels responsible
My guess would be that you might have a bad brake hose to one of the front calipers.
During hard braking, inertia would cause the weight of the vehicle to shift forward towards the front wheels. This is because the momentum of the vehicle is being slowed down, leading to a weight transfer from the rear wheels to the front wheels.
Your rotors are probably warped from getting hot during braking and need to be "turned" or replaced. I suggest you take it to a brake shop or dealer.
Front wheel brakes offer several advantages in terms of safety and performance compared to other braking systems. One key advantage is that front wheel brakes provide better stopping power and control, as they are able to distribute the braking force more evenly and effectively. This can help reduce the risk of skidding and improve overall handling and stability during braking. Additionally, front wheel brakes can also help to prevent the vehicle from veering off course during sudden stops, enhancing overall safety and responsiveness on the road.
I beleave it's Front 60% and Rear 40% that is distributed between them both
Dual diagonal braking is where the brakes are on two systems right front and left rear as well as left front and right rear. This is to give even braking in a partial system failure
The brake ratio in a front-wheel drive (FWD) vehicle typically refers to the distribution of braking force between the front and rear wheels. In FWD cars, a common brake ratio is around 60-70% of the braking force applied to the front wheels and 30-40% to the rear wheels. This distribution is due to the weight transfer that occurs during braking, which places more load on the front wheels. However, the exact ratio can vary based on the vehicle's design and intended use.
Front brakes are primarily responsible for slowing down a vehicle during braking, as they handle a larger portion of the vehicle's weight transfer forward when stopping. This results in greater stopping power and heat generation, necessitating stronger materials and designs. Rear brakes, while still important for overall braking performance and stability, typically handle less braking force. Their primary function is to balance the vehicle's braking dynamics and prevent rear wheel lock-up during hard stops.
Possibly a rotor scored badly or warped from overheating, maybe a piston that's sticking. Either way, essential to strip the front brakes and check everything.
The front brake pads have wear indicators that will cause a squealing noise during braking when the pads need replacement. If you don't have this noise during braking they don't need replaced. Rear pads should last through 2-3 sets of front pads. The brake fluid should be replaced every three years.
