Just put all new drums, shoes, cylinders and hoses on my '69 C10, no power brakes.
When you press the brake pedal it vibrates badly, seems to be a higher frequency than what I've experienced with warped rotors. Is there some other possible cause or is it simply warped drums (out of round)? Doesn't do it when using the parking brake so presume it must be the front, can't tell if it's both or just one, doesn't seem to pull to one side or the other.
New drums from the Irish chain, obviously expected them to be perfectly smooth. Any help appreciated.
