Reader Question: My 1998 Ford Mustang GT 4.6L has recently been fitted with rear rotors and pads. When first drove the vehicle for a few miles the rear brakes got very hot, the rotor went blue and I had to pour water over to cool it down. There was also blue smoke. Is there something else I should have done?
Is this normal?
What can I do to stop this?
This is not normal, something is in a bind or rubbing and causing the brake pads to drag against the brake rotor. I would triple check your new parts to make sure you have the same parts as the old ones, same shape, size, etc. etc.
Check the calipers and make sure they move freely and are not sticking. You might have to true (machine) the rotors a little bit if you bought cheap after market rotors that might be a little thicker than they need to be.
Check the emergency brake cables and make sure the emergency brake is not adjusted to tightly causing the brakes to drag.
Last thing would be to try gravity bleeding the brake system. Open all brake bleeder screws and allow gravity to suck out the brake fluid and hopefully any air that might be in the system.
Make sure to keep the brake master cylinder full of brake fluid…this can take an hour or so.
