A trusting member of local AH Club wants me to help him with a constant friction noise emanating from left front wheel of BJ8.

He's been told to put "organge goo" on brake pads. Found out that it's actually called "Brake Quiet".

What do you think? Even though I have an AH, as you know there it has virtually nothing in common with the "big Healey". Is this a potential fix? Other suggestions?

Really appreciate it gentlemen and ladies. We're jacking her up and pulling the wheel this Saturday, so I'll be looking for your advice.

Thanks for your help.

Dave, a suggestion. First go for a road test to verify the noise. Is it occurring just when braking? If so, focus on the brake pads.

Remove the pads and examine them.. The "friction" noise, with good pads is a metal vibration transfer noise. Look at the edges of the pads, and the back of the pads, and where the retaining pins go through the pads. Anywhere there is shiny metal, showing metal to metal contact you need to insulate that. Best insulation is a high temp brake grease... Lightly on the back of the pads where the piston contacts marks are(lightly being heavy enough to not wipe off with a single pass of a rag, but not where it is dripping off the pad. Lube the edges of the pads. This is an area, that the majority of people are not aware of noise contact emanation. Then through the pin holes(and I lightly coat the pins)..
Chamfer the leading edge of the pads with a file or grinding wheel. Reassemble and good to go.
 
Dave -

The brake squeaking on disc braked Healeys almost always is a result that some PO or half-assed mechanic replaced pads and threw out the anti-squeak shims in the process. All healeys need the Girling anti-squeak shims in there to prevent squeaking.

Buy a set of anti-squeak shims from your favorite Healey supplier, whomever that may be, and put them on the car.

FYI, the squeak goo will not work because the brake piston will wear through the goo in no time.

Avoid the goo.... always, always avoid the goo.

I replaced my pads last fall and now have the squeak.
I put the original anti squeak shims back in with the new pads.
I guess they should be replaced with new ones at the same time the pads are replaced ?
Or could I just spray some " quiet brake " on the back of the pads between the pads and the anti squeal shim ?
I have used this " quiet brake " out of a rattle can on other cars many years ago and it always got rid of the squeak.

Ed - the quiet brake goo works ok if you put it inbetween the shim and the brake pad. I was saying you can't use the goo on the back of the pad w/ piston only... that doesn't work.

The shims should work, whether used or new. I suspect that if they aren't working that'll be because they are stuck to the back of the pads w/ corrosion/dirt... they work best if clean & loose or if you want to goo them on the back of the pads, that should be ok as well, but less than ideal if you ask me.
