Impulse buy: 2015 Fiesta ST

[Senor_Taylor]

Track car ended up not being ready with the cage builder, so I towed this thing to Summit after throwing on some parts store brake pads and old summer tires I bought on the cheap in Charlottesville.

The car felt very good for the few laps I drove it. A lot more neutral than the GTI was, maybe even feeling loose in the rear at times. It was quick, stopped well, and the turn in was very very good. I was really afraid to get the brakes hot in my first session so I took it really easy, then I saw my coolant temp hit 241 and I pulled in.

Sitting on grid for the session before my TT checkride and I realized the brake pedal would sink down to the floor very slowly if I kept pressure applied. Dangerous? Maybe. Something that concerned me? Yes. I ran another bottle of RBF 660 through it and the pedal didn't get any better. It seems to be either a bad master cylinder, or just a $5 brake switch that freaks out the ABS system or something. I decided to park the car and can my TT checkride. Another day, I suppose.
