04 WRX
Ap fronts,Brembo rears .
Is there a bigger master cylinder i can fit to give more pressure?
All ideas welcome

 

What pads are you using?

 

DS3000 front
PF rears

 

I'm assuming you feel they lack initial bite on the road? Or is this a track car?

Which PF compound are you using?

 

its a road car.Not sure on the pf compound i will ask Ryan later when i collect the car.
Before i had the AP calipers fitted i had the black brembos off the sti hatch,much better bite.

 

What pads did you use in the Brembo's?

DS3000 wouldn't have been my choice for a road pad, they are more of a track orientated compound.

I personally would have fitted matching compounds front and rear also.

Do you find the bite gets better if you get some heat into the brakes?

 

They were fitted under advice.

 

I would suggest DS2500's or PF Z compound pads for road use that will also stand up to the odd track day.

 

So you think it is down to pad choice and not the brake master cylinder not up to the job?

 

I would definitely look at changing pads before looking into things like brake master cylinders.

When was the system last bled?
What fluid are you using?
What hoses?
How does the pedal feel?
Does your current set up improve if you get some heat into them?
