At Blyton this weekend I wasn't happy with the braking on my car. The brake pedal had longer travel than normal but it didn't "pump up" with repeated presses (so not pad knock off). It was "slightly spongy" but not everso. The car stopped OK but there wasn't much feel - it was hard to know when a lock up was imminent.
I have Caterham AP big brakes, the standard master cylinder (never been a problem before), Pagid RS14 pads on the front and Pagid RS4-2 pads on the rear. I have flexible hoses on the rear calipers.
The rear pads are pretty shot now so need replacing and I suspect the fronts have seen better days.
So the questions are:
1. Any thoughts on the cause of the long, slightly spongy pedal?
2. Should I change the master cylinder to the AP item? What difference does it make to feel, travel, etc.?
3. What is the best combination of currently available pads front and rear? Is there a new leader?
I never got on with Pagid RS15 fronts as they just glazed over with road use. My main use is sprint and hillclimb with some road use and the occasional track day/test day.
I will be replacing the fluid with a good quality standard DOT4 fluid. I don't think there is any need for racing fluid but happy to be convinced otherwise.
