Quick check for cause of brake pedal pulsation

Doing a good visual inspection is alway key to solving the problems your faced with when it comes to repairing your vehicle . In this case a good visual inspection shows us everything we need to know to address my customers concern with his vehicle . The discoloration and wear on the rotor shows us which rotor has been causing the pulsation that my customer has been complaining about . The proper way to test for this would to be use a dial indicator but sometimes there isn’t one on hand so these are some good tell tail signs to look for
Hard spots , heat checks , glazing that this in patches on the rotor, improperly torqued wheel lugs ..
Good luck and hope this helps
