Default Warped Brake rotors? - Turn or Toss? See pics!

Has anyone tried Brembo rotors on the Bonneville?

For our 95 SE, the following Brembo is available:
:# 27038
Main Category: Brake/Wheel Bearing
Sub Category: Brake Pads/Shoes/Rotors/Drums - Front
Qualifier: PONTIAC
Description: Front Brake Rotor
Manufacturer: BREMBO BRAKES
Additional Description: Front ; Min thick (mm) 30.7; Years:1995-1996; Per Car Qty:2;
Your Price: $ 43.95

Since Bendix rotors are now made in China and not of the previous quality, I'm looking for an alternative. I have been told that Powerslot uses Brembo blanks, so it seems that Brembo rotors would be a suitable OEM replacement. A pair of eBay drilled and slotted rotors would be cheaper, probably made in China, but after the relative short life of the NAPA rotors on the car now, I don't want to test rotors again if someone has experience to share. Only the Powerslot rotors are still available from the brands previously recommended, but at twice the price.

Thoughts ?

I've got Bendix on now and my previous ones died before the first pads were dead...pretty sad. I don't know if the replacements I just got were from China, but either way if these die I will be looking at Brembo because of them being a reputable company... The only thing that threw me was that PartsAmerica.com (Advance Auto parts online) didn't display them for our car, but that does not mean they don't make them and obviously you already have the part number...


I just hate to tell you I don't think you are going to get much of a review on here, with how long I've been on here I've never heard of someone saying they used Brembo brakes..but hey...it'* always possible and I two would also love to hear a review/price/info....

Auto Parts Warehouse (and autobarn) stock the Brembo rotors. Looking at possible brake pad choices Isee PBR Metal Masters reasonably priced and they have a good reputation on other cars. A better option would be to go up to HAWK HPS SERIES BRAKE PADS for twice the price. Given the recent posts about some ceramic pads and warping rotors, I wasn't considering ceramic pads.

I found some good reviews about Brembo OEM blanks with HAWK HPS pads on other cars, so I am seriously given them some consideration. I know Andrew briefly considered slotted Brembo rotors (for 1997 and newer) before ordering the Bendix (now made in China) rotors that aren't what he expected.

Any experiences with the Metal masters or HAWK HPS pad on the Bonneville?

Can't say I've had experience with Hawk or the said other. I think my friend uses Hawk on his 300zx Twin Turbo and they are good....

I ordered the Brembo rotors and Hawk HPS pads.

I'll report on initial impressions when i install them.

Hopefully they don't come in a Made in China box like Andrew'* Bendix rotors.

I installed the Brembo rotors and Hawk pads last night, installation went easily. The Brembo rotors were Made in Mexico and don't appear to be as heavy as the Napa rotors they replaced. Weight of the Brembo rotors is about 16 pounds each. Broke in the pads according to Hawk'* directions Stopping is smooth but I won't be pushing them for the first 100 miles or so. Hopefully they are gentle on rotors as advertised.

On the old rotors the discs were a discolored blue over most of the braking surface (except at edges). On our Porsche 968 with Zimmerman rotors the braking surface is universally bright, no blueing). As you can see in the photos, three of the four surfaces had the blue discoloration, while one looked normal. Is this due to dragging pads, or is it nothing to worry about? The old pads were barely worn. I wonder if they contributed to the warping of the rotors. The rotors were barely worn as well, should they be turned or discarded? Must be the frugal side of the family that hates throwing away anything that looks almost new.
