I have rear drum and front disk brakes. For the front i have hp racing 6p calipers, pads, and drilled/slotted rotors. The company from what i understand will not sell pads and rotors anymore. My rotors and pads are worn down to where i should replace them but untill i can decide what to do they should still work.

I just had my rotors turned (because of rust) and now they are cleaned up pretty well, same with pads. Pedal for the most part feels pretty good, you can tell a slight improvement in it when starting the car (guessing master cylinder and booster are good)

so even with the rotors turned the car still stops poorly. Any guesses as to why? (Do 6p brakes usually require getting an upgraded booster?)

 

What car?
What brakes?
What are the brake piston diameters?
What are the brake rotor diameters?
Is the pedal hard or soft?

 

its a 1996 honda accord
(Front)Disk Brakes: HP
(Rear)Drum Brakes: Stock
stock master cyl
Rotor Diameters: 310.21.46mm
Piston Diameters: ?
pedal firm, booster function verified.

 

Can I assume that these once worked well?

 

talk about a huge braking imbalance....sheesh

 

1) u need a booster only cause you need a different master for the 6 pot, because our cars were not designed to have a 6 pot most stock calipers are only 1 cylinder with a 13/16master tiny, and since your upgrading to more cylinders their "area/diam" of the pistons are different sizes now, therefore requiring more fluid to press the piston to pad, pads to rotor, and your stock master may not be able to perform with those tasks.



-faded.....

This is a good point. I assumed that these were intended for the car.
