Clicky Brake Pedal

[sh0rtlife]

well youve got a few options

the arm rests on a shaft, then below that is a pin and push rod(these often click on many makes n models) then at the end of the pushrod it goes into the power booster and thru the firewall..again a good click point..youve also got the brake switch itself..which if loose or going bad will click or squeek

if its inside the car stick your head under the dash and wiggle it around and finding it isnt hard
