There's a few ways, by far the easiest and cheapest will be buying different pads front and rear. More bite in front and less in the rear will cause less braking oversteer and more predictability under hard braking. The other way is to install a proportioning valve into your braking system where you manually need to open or close the valve to change the brake bias.

 

brake bias referring to either front or rear braking harder then the other?

 

Yes, biasing changes how much of the total work of braking is done by the front and rear brakes. Pulling the e-brake is like 100% rear bias.

Would pad and rotor wear rates be good indications of brake bias?

I beginning to wonder if Honda puts in so much front bias in the Prelude so that spins are less likely when braking in curves, off-ramps, etc.

 

More than likely they try to make the car stupid proof so you can almost be assured that it is. What pads are you using now? Unless you're willing to swap the pads out at the track you're not going to find too much in this territory esp with street tires.

 

Hawk HPS with OEM rotors, F1 GS-D3 tires.

I going to start shopping around for the brake bias hardware too see what installing and adjusting it will involve.

 

I really wouldn't worry too much about this especially if you're just using the HPS's and not something with more grip. All you'll really be looking for is the proportion valve and a method to move it from the cabin. You'll probably find all the parts you need at racerpartswholesale.com. I'd invest in more track orientated brake pads first.

 

I'm thinking of moving up to HP+.

How do those propostioning valves work? Do you just install them in the lines for the front brakes and adjust the valve to reduce front brake line pressure? I'm looking a pictures of them and they only have two places to connect the brake lines.

 

I found more info at Tilton Racing.

Brake proportioning valves are actually brake pressure reducing valves that kick in after a preset brake line pressure is reached. At that point, brake line pressure increases at 1/3 the rate compared to the brakes (rear) that don't have this vavle installed.
