I finally got my TSX in for service. They fixed my clicking cluth pedal by replacing the master cylinder. They also replaced my front calipers since the original ones were badly rusted. They didn't have time to fix the squeaking driver's seat or the front rattle due to lack of time.

Anyway, they gave me a loaner TSX with only 3k miles. I noticed the steering was slightly tighter and the brakes were more sensitive than my car. I feel like my brakes are insufficient at times. Could brake fluid be a factor?

Btw, I already had my rotors replaced earlier this year.

 

If you've run your brakes hard, then it is possible that you've boiled your brake fluid, which can result in a loss of pedal feel and braking power. You can request a change of brake fluid, but this would not be covered under warranty.
