I know brake fade and pad opinions have been discussed ad nauseum around here, but I'm not finding much pertaining to earlier cars.
At Mosport this weekend I noticed significant softness in my brakes, and not just towards the end of the day. I was getting it by my 3rd run of the day, even towards the end of my 2nd run. Should I be looking to upgrade pads, or is it most likely a fluid thing?
Here's what's there now:
Brand new MC (replaced last year)
Brake fluid changed at the same time (this was my 2nd track event since changing, wanted to change before this one but simply ran out of time, brake fluid is DOT4)
Textar brake pads
Aluminum S calipers up front, steels in the back, I'm assuming they're the original calipers, no idea if they've ever been rebuilt.
Engine is stock 2.4T, and probably not running at full potential (could use a tune-up). Speeds along the back straight at Mosport reached maybe 150-160km/h (95-100 mph) with a tailwind
Braking on the street is more than adequate, but probably could be stronger. I can lock the wheels, but have a very difficult time getting the tires to chirp under threshold braking (I've done it in other cars with no problem, so I'm familiar with the technique). I want to do the next DE in early June, but need to get this addressed first.
Thanks!
