ok i took my car to get it tuned and the guy drove my car for about 3 mins and he was complaining that my brakes are really hard. so i told him they have been hard ever since i bought the car back in 97. i put in a gsr rear disc and it just as hard on the petal from the day i got the car. brand new dot 4 brake fluid. he told me that my brakes should be soft. and he showed me his brakes and it felt like there was air in his lines and he told me this is what they should feel like. is it try the brakes should be soft? or stiff when i step on the brakes? i have my stock front disc but gsr rear disc with a gsr p. valve could it be because he has stock front disc with rear drums? let me know. just as a pointer when i go to get my car inspected they never told me a thing about my brakes!
