Brass brake bushings?

[632 Regal]

Anyone know anything about these? Benefits? Drawbacks?

Hey! Read the ad man ,it says "Intensifies the excitement of owning a BMW"

I know Martin in bellevue has them on his front e31 850 single piston brakes. I'm getting some because I'm rebuilding my brakes.

WHo doesnt want to intensify their dirving experience? Although i suppose a dual blowout at 70mph would be pretty intense too...

i read that to mean noisy as ****, i hardly ever need to screw with the standard rubbers, usually the only time they need looking at it's because some ass screwed them up, i do several dozen brake jobs a year and sell many calipers from the yard

I have them, they are in my new calipers but not im my car yet.

will report on their effectiveness

Heres my thought: BMW designed them the way they are for a reason, and its highly unlikely they did it to save money (dont see too many cost cutting features on these cars). Something rubber rather than metal is probably meant to transmit less vibration. Sounds like something BigKriss would like (ie, race car setup).

I have those installed in both front and rear. Find them to be able to quiet down my brake and offer less brake chatter. And not sure if it is just me or not, the brake actually grab a little better and sooner than with rubber bushings.

Agreed, they hold the caliper firmer in plane to the rotor. The heavy 850 single pot front calipers wore the pads significantly more at the inner radius area, without the brass bushings. They stopped the pad squeal at the rear.
I think the rubber pieces can only take so much heat with the heavier calipers; they were very soft on 1 side.

so replacing the stock rubber ones would probably be an idea at my mileage...ill check out the part numbers and add them to the growing list.
