I have a 2007 mazda 5 touring model with 43852 miles on it. I had to replace the tires at 37700+- miles on it due to tire cupping and the tires being worn down to the liner. Before I replaced the tires I had a whole body wobble at any speed so I got the alignment done, it was good, i got the rotors turned, and then I finally replaced the tires. New tires are good so far after 6000+- miles on them. Brake wobble went away after rotors were turned but has come back again in the las month. I don't brake hard or drive crazy. The last problem is the a/c compressor belt slips when it rains. I can see no way to adjust the a/c belt tension. Does anyone know how to do this? Any way to fix the brake rotor warping? Should I put after market drilled and slotted brake rotors on it?

 

It may be that soft braking builds up heat in the brake discs, I get the same problem but I seem to get it eventually on all cars I've driven, it just takes different amounts of time dependent on the discs.

A VW Golf I had once used light up the pads and the discs always wore out with the pads, same with a Peugeot 406 new pads and discs every 40,000 miles.

These discs just seem to warp sooner

 

I don't know what causes it. I never had this problem on the 3 Acura Integras I had 1988(sold), 95 GSR(totaled) 1994 GSR(traded in for 2004 Mazda 3s 5-door no braking problems or any problems yet) I am thinking of just getting higher performance rotors. I think the brake rotors on this van are the same ones used on the 3s hatchback but the 5 is so much heavier. I don't know that for sure just guessing. Do you know how to adjust the belt tension on the a/c compressor? Thanks
