Is front or rear brake bias better?
Is front or rear brake bias better?
Brake bias helps the driver maintain control while braking. In most cases, the front brakes provide more force than the rear. Optimal bias is when all 4 wheels lock up at the same time. However, there is no magic number.
How does brake bias affect front tire wear?
This can also cause rapid front tire wear due to front tire lockup, especially of the inside tire which is the first to lock up. Reducing Front bias: This puts more braking on the rear tires, which, within limits, improves braking efficiency. Too much rear brake bias, though, hurts performance in two ways.
What does a 52% brake bias mean?
Brake bias – Indicated as a percentage. This indicates the relative amount of brake pressure applied from the master cylinder (s) to the front brakes. E.g. 52% would indicate that the front brakes were receiving 52% of the brake pressure and the rear brakes would be receiving 48%.
How to get perfect brake bias in a car?
At first glance, one could surmise that in order to achieve perfect brake bias you could just: 1 Weigh the four corners of the car 2 Design the front and rear brake components to deliver torque in the same ratio as the front-to-rear weight… 3 Win races More …
What happens when a car has too much front bias?
If a car is too heavily front-biased in the deceleration range it typically operates in, it will wear front pads more quickly due to the fact that the rear brakes aren’t doing as much of the stopping work as they could be.

Why is there bias in the brake proportioning valve?
However, one critical factor in establishing bias – the mechanical brake pressure proportioning valve – was left out of the discussion. After all, one can only take so much of this brake bias talk in one sitting. That said, we are back to share the intricacies of just how brake pressure is distributed to the front and rear of the vehicle.
If a car is too heavily front-biased in the deceleration range it typically operates in, it will wear front pads more quickly due to the fact that the rear brakes aren’t doing as much of the stopping work as they could be.
Do you have to proportion front and rear brake lines?
The effect would be to make your vehicle rear-biased before you could say “terminal oversteer.” Front brake line pressure should always be left alone – only the rear pressures should be considered for proportioning. 3. In all cases, the basic brake system balance needs to be close to optimized to start with.
