for a few months now my brake peddle has pulsed when stopping. wheel bearings appear fine with little to no movement and the calipers and backing plates appear to have no movement any ideas? appears worse after driving fastish but that may just be cos i am going faster. 
i think it started after i replaced the rear diff center and axle seals but i cant be sure that that is when it did start. |

last time i had this problem i fixed it with new pads they were not wearing square. if yours are not wearing well i would suggest filing/sanding on concrete ect |

Hot spots can also occur when you drive into water and put your foot on the brakes when they are hot. |

i reckon royce is on the money. have cleaned up one side and it is a little better however the four studs are quite loose in there holes so i dont think it will ever be properly fixed. the car just needs to hold together for about 1000km and then i can fix everything properly. |

I found on mine sometimes pulling the drum off and rotating it 90 degrees and back on would fix it |
