Brake noise?
Rebuilt the braking system on my '77 a few months back, Installed new slotted rotors,insulated ss o-ring calipers,pads,ss lines & hoses.
Ever since ive been getting a squeaking noise that can be heard at slower speeds-squeak gets faster with speed,louder when brakes applied,also makes a 'moaning' noise when pulling off from a stand still,mainly coming from front calipers.Its almost like the brakes are slightly on all the time?
Front end of car pulls to left when braking at speed also.
Up to now ive tried changing the semi-metallic pads for organic,Shimming all the rotors to within .003",bleading with a second person on the pedal/mighty vac/and today with a motiv pressure bleeder. Had about 6 litres of super dot 4 through the system up to now so im pretty sure thairs no air left in the system.
After spending all this time and money on the brakes i really dont want to have to live with an annoying squeak
. Any help,ideas,guesses much appreciated.

I've experienced the "moaning" when just starting to move. It was the emergency brake dragging in that case. Maybe a gravity bleed session will also ensure no air. A good cleaning of the discs with clean pads??? These noises are definitely irritating. Good luck.
