Just surface rust on the rotors wearing off in the first few stops in the morning. As long as it doesn't continue throughout the day you're fine.
Just try taking off the pads and rotors and roughing them up with a little sand paper. The oil they use to store the rotors with will film over sometimes. Same thing happened on my friends Subaru. I used the sand paper and saved his dad $700 on all new brakes.
as a double check, did you use high temp/brake grease on the back of the pads, caliper slide bolts, and the caliper/pad slides?
Spray the steel part of the pads with disc brake squeel. The squeek yer hearing is actually a vibration when their cold after a few stops they heat up and expand. The disc brake squeel will take up any inperfections in the pads and yer nasty squeel is overwith...
not to hackjack this thread but since we're on the subject of sqeaking brakes, I also have a few questions. Just until about a month ago i got my 86 cutlass done and have been driving it. Ever since about a week and a half ago when driving at any speed there's a annoying sqeak coming from the passenger side brakes, when you touch the brake pedal or slow down it goes away but when you let off the brakes it appears again.These brakes are in really good condition and there are no other problems with them at all except for the noise, Its really annoying so does anyone happen to know what could be the problem.
blake, i put the car on the lift and moved the tires around and there was no sound, i have reason to believe its something with the brakes, could it be they're slightly warped enough to rub? I guess i should double check everything next time its on the lift, it has been sitting for 10 months.
every new brake pad needs to be bedded-in with the rotor and the company who makes the brake pads you bought ought to have instructions in the box. I run EBC brakes and if I don't break them in properly I've wasted over $80 on a set of pads. I would suggest contacting the manufacture of the pads you bought to find out the proper procedure in breaking them in...... here are the break in instructions for some of the pads out there.
AKEBONO
400 to 500 miles of moderate driving is recommended. Consumer should avoid heavy braking during this period.
ATE
400 to 500 miles of moderate driving is recommended. Consumer should avoid heavy braking during this period.
BREMBO Gran Turismo
In a safe area, apply brakes moderately from 60mph to 30mph and then drive approximately 1/2 mile to allow the brakes to cool. Repeat this procedure approximately 30 times.
HAWK
After installing new pads make 6 to 10 stops from approximately 35 mph with moderate pressure. Make an additional two to three hard stops from approximately 40 to 45 mph. Do not allow the vehicle to come to a complete stop.When completed with this process, park the vehicle and allow the brakes to cool completely before driving on them again. Do not engage the parking brake until after this cooling process is compete.
NOTE: Hawk racing pads (Blue, Black, HT-10, HT-12) may require a different bed-in procedure. Contact your sales specialists at the Tire Rack for racing application information.
POWER SLOT
Follow the brake pad manufacturer's recommended break-in procedure taking care not to produce excessive heat in the system. Avoid heavy braking for the first 400-500 miles.

For Gransport GS6 Carbon Ceramic Pads —
Step 1: Make 10 stops from 30 mph (50 kph) down to about 10 mph (15 kph) using moderate braking pressure and allowing approximately 30 seconds between stops for cooling. Do not drag your pads during these stops. After the 10th stop, allow 15 minutes for your braking system to cool down.
Step 2: Make 5 consecutive stops from 50 mph (80 kph) down to 10 mph (15 kph). After the 5th stop, allow your braking system to cool for approximately 30 minutes. This completes the break-in of your pads to the rotor surface.
During Steps 1 & 2, a de-gassing process occurs which may produce an odor coming from your pads as they complete the break-in cycle. This odor is normal and is part of the process your pads must go through to achieve their ultimate level of performance. The odor will go away after allowing your braking system to cool for approximately 30 minutes.
As with any new set of pads, do not tow a trailer or do any hauling during the break-in period.
Full seating of your new brake pads normally occurs within 1,000 miles.
