Hey! I was driving the GR. The brakes in 100% stock form have some "issues" dealing with the temperatures of heavy work. I managed to get the pedal really soft when pushing hard. I have since then changed the brake lines to steel braided lines, and changed the brake fluid from the stock DOT4 to Motul RBF 660. There was no brake fade, or no difference in feel throughout the lap.
@@GreatMotors thanks for quick reply! I have 2800 km on my GR and noticed that braking and feel is not 100% and thats on street and winter tires... So much worse on stickier tires and circuit!
@@jagymeister I never drove the GR Yaris on winters. But what you feel might be 100% due to the tires. Winter tires are notorious for shitty feedback. I never had any complains towards the brake feel of the Yaris when stock, just that the brakes were not that resistant to fade. The fluid and lines helped to get a slightly tighter brake pedal, and improved the temperature resistance massively. For you I would start with trying out the car with summer tires (I am using the stock PS4S) and go from there.
Did you noticed brake lines and fluid on GR Yaris over stock?
I will get my friend to answer you directly
