2004 Rear brake Rotor upgrade

Post by hosszz4 »

Hi,

Can the rear rotor on the 2004 small blocks be repaired?Different fasteners, or aftermarket options, or do I need to buy a complete rotor and chrome hub and attachments? I can touch my rear rotor and lift it a quarter inch off the chrome center hub and sway it an 1/8 inch side to side. Rattles at slow speeds banging into the brake pads.

I have 40,000 hard miles on this rear rotor.

if anyone has a good used one, I'd happy to consider buying it. Thanks in advance

Aldo... Mountian has take offs. Might save a few bucks. There is a rotor without the hub on e-bay. Can you tell which part is worn?

The part that is worn is not 100% clear...I think its the 10 buttons and clips that hold the floating rotor to the chrome hub, but cant tell if that means the rotor is worn in the places where those 10 buttons fit.

On my 2004 small block the rear brembo rotor has a minimum thickness requirement of 5.4 mm, mine is 5.7mm currently. Its a 320mm rotor or 12.5 inch. It moves about 1 mm up or down and side to side and rattles. Similar Rotor as the front except the front has wear minimum of 4.5mm, with no rattle and rear has wear minimum of 5.4mm, so thicker rear rotor. I just wonder if the buttons used to mount the rear can handle the heat and as one wears they tear up all the others soon after.

If there were thicker buttons that I could replace, I could still use this rotor, but dont know if such animals exist. That other rotor on Ebay, looks like a Chopper City part. Might give them a call and see what Marv says.

Cheers

Think I have the solution now...

Spoke with Marv....he adds an additional washer to the Rotor buttons to address this problem. So you only need half of the buttons to have the additional washer to stablize the rattling. My rotor is fine, so dont need another rotor.

I decided to buy a set of 30 V8 embossed rotor buttons from Marv for the extra bling as well.... :mrgreen: just couldnt resist and Marv will send me these extra washers as well.

Also bought some under the tank Chrome Sidepanels for extra bling :mrgreen: What can I say...I'm addicted to bling...
