I have a Sequendra (converted Sequoia). I have StopTech on front and oem on back, but the brakes are still not stiff enough for me. Requires long push and lots of pressure to get some bite. Suggestions? Are there options for bigger rotors and pistons, and would that make a difference? Steel lines? Different master cylinder? I'm not mechanical so I'm looking for recommendations for making the brakes as responsive as possible. Thanks!
