My car handbrake has became s**t, you can push my car when the handbrake is on. Has been getting worse gradually. I took the car to get the brakes tested and the guy said that the rear brakes were fine but the handbrake wasn't (yes, thats why i brought it to you!!!!!!). Anyway i was reading about adjusting the cable and it shows that you turn the adjusting secrew handle thing, but my car doesn't have the handle just a screw that i cant get a grip of to turn. Is this normal? Is there anyway i can turn the screw to tighten in without the handle?
