After driving my girlfriends rt the weekend, it became clear to me that there is a problem with the brakes on my valver. Ive driven her car before and didnt notice a problem so it must be newish. the pedal goes quite far down before any stopping happens (on the rt it was right at the top), so i bled the brakes today and the problem is still there. i also took the back wheel off to inspect the rear discs and pads. the pads still have some life left and the discs are worn and corroded but not too bad. i think ill replace these as a matter of cause tho. The front discs are two months old and the pads are kevlar too.
Could it be the master cylinder or anything else???
Help appreciated!!
