Hey everybody -

I'm having brake problems, see what you think. . .

In an attempt to quelch my squeaky breaks (SC400), I put new brake pads on front (Bendix) over new rotors. I took her out on the road and they seemed to squeak more than before. So, I gave it a few more days, no luck. I tore the rear brakes off, the rotors looked to have less than 10k miles on them and the pads looked the same. I cleaned the whole assembly, even the E.B. drums. One of the drum shoes had glazed over so I grinded that off, they even looked new. Everything seemed tip-top. So I lowered her down and now she sounds like a SCHOOL BUS!!! What should I do? Am I cursed? I've only had it for 5k miles and I know the previous service history. Thanks for any input.

Are the Bendix semi-metalic or organic? Stock is organic. Did you put the metal backings back on along with the two wire do-hickeys between the two pads? Did you bed down/break in your brakes? As a last resort, try putting a slight bevel on the pads.

Yeah I got the organic, and I put both the metal backings and anti-squeak thingy's back on. However, I didn't "bed down/break them in. What does that entail?

1. GEOMETRIC ALIGNMENT OF PAD SURFACE TO BRAKE DISC BASIC BEDDING IN

3-4 stops with light to medium brake pressure from approximately 150 km/h (90 MPH)
to approximately 100 km/h (65 MPH).

Distance between each brake stop is approximately 300-400 meters (300 to 400 yards).

The pads should not reach temperatures above 300-400 Centigrade (550 to 750 Fahrenheit)
during bedding in.

Blocking of the air ducts might be helpful to reach appropriate temperatures quicker.



2. IMMEDIATELY AFTER BEDDING IN AT HIGH SPEED

One stop with medium to heavy brake pressure without allowing the brakes to lock from
approximately 180 km/h (110 MPH) to approximately 100 km/h (65 MPH).

Recovery stops with light brake pressure 2-3 times.

Repeat the high speed stops, including recovery stops, 1-2 times.

Allow a cooling-off distance of approximately 500 m (500 yards) between high speed stops.

BRAKE DISC

Pagid brake pad material can be used either on solid, grooved or cross-drilled discs.


MOUNTING NEW PADS ON USED DISCS

Edges of pad surface should be filed roughly 45 degrees to ensure that the pad carries fully
and evenly and is not touching the edge of the disc.

Do not use discs which are pre-bedded, or have been used with friction material other than PAGID.

 

Wow, thanks for the info. People really do this? I'd hate to have to explain to the cop that I was doin 110 because I was breaking in my brake pads. I read about this procedure once before, I just didn't know what to think of it. Have you done it before? Did it work?

 

Try buying new shim kits. Grease them well with the packets provided.
