Right, I have had my ST170 kit fitted this weekend, had my ABS removed too. I too have a bit of "pedal travel"
It was quite bad after we first bled the brakes up, dont get me wrong the brakes are great when they bite but the initial bit of travel is there when you brake. This was on Saturday, since then my pedal has improved slightly and after the 50 mile drive home it has got better (steady braking as the pads have a couple hundred miles to bed in yet)
I think the problem is as mentioned above by
ON-UJAH
Obviously 4-pots or any other brakes with larger pistons in the caliper than standard will increase brake travel
Which is exactly what Gadget said to me (who fitted the kit) as there is a larger piston for fluid to fill. I'm tempted to get a new master cyl / resi as I fear mine may have a slight problem...i'm still thinking about that now, I think my brakes are back to as good as they were before fitting the ST kit and ABS removal, there is still travel but not much in comparison to any normal escort
(MY pedal certainly does'nt go no where near the floor.)
