How To Isolate A Brake Pulsation

This is one of those useful tips that can help you isolate where a brake pulsation is coming from, front or rear. Keep in mind this only works on some systems and if you have a pedal type parking brake be VERY careful doing this especially if you’re on a public road as the rear wheels could lock up which would make for a very bad day, also be careful on wet roads for the same reason. Otherwise check your rear brake set up to find out if it’s even possible to differentiate between the 2, remember if it’s a disc brake set up with a drum brake inside the disc this method won’t work so in that case you’re just going to have to go by ‘feel’ and guess where the pulsation is coming from unless you have a micrometer with a magnet attachment that you can use to check for the runout.
