Hi guys,

I've just completed a brake conversion on my 1965 AP6 Valiant from drums to discs. New rotors (solid, dimpled and slotted), pbr calipers overhauled (cleaned, new seals, greased pins), new hub bearings, new bendix general ct pads, anti-squeal shims, brake grease, VH40 remote booster (new) set-up with reconditioned master cylinder and new brake fluid of course. Did the setup myself and got mechanic to check and rebleed system. Brakes work beautifully, but after a few km's there is a terrible squeal at low speed.

I suspect it is the pads as I had originally put the 3M self adhesive backing on the back of the pads for the 1st couple weeks. The squeal started, so replaced the stick on stuff (which looked pretty stuffed) with stainless steel shims and brake grease. The squealling returned.

Suspension is new and brake conversion has been done properly. There is no shuddering or vibration at the steering wheel and the car stops straight and true.

I have a few sets of original old pads that are only 1/4 worn (have asbestos in them). If I can 't find a solution soon I will be cleaning the rotors (clean up any pad build up) with 120 grid sandpaper and brake cleaner and using the original pads.

Can any of you guys see something I've missed. I can replace the solid, dimpled and slotted rotors with standard ones is my only other alternative.

Any ideas/comments would be very appreciated.

Regrds,

Bare Metal Maz
