Pulsating Brakes

A very common issue with any vehicle is to do with your brakes pulsating. If you are pulling off a highway and your steering wheel is shaking, or your seat then you may have a problem with your brakes that needs to be looked into.

On this particular video blog, the ford F150 we worked on, the customer was experiencing problems pulling off the highway and their steering wheel was beginning to shake as they slowed down to a stop. The issue he thinks was caused by the previous weekend where he used his truck for towing heavy loads and this highlighted the problem. There is some indifference in pad wear and it needs to be evened out to stop this problem continuing to occur. See video below where master technician, Mike Reynolds explains exactly what is going on and how we solve this problem;

Cracked PadsAlso on this vehicle, the pads were cracked as you can see by the picture to our left;

Cracked pads are caused by one thing, excessive heat. When they are thin, there is not enough material left to help dissipate the heat and so it stays in the pads too long causing the big crack you can see here.

 

We can also show you pictures highlighting what it next. The next stage is the machining process to machine the run out out that will take care of the customers brake pulsation.

The 3 pictures above represent three different stages of the cut.

From left to right as you look;

LEFT PICTURE - Cut #1 – Shows a lot of low spot and also shows where the bit did not contact the friction surface of the rotor uniformly. That is where there is a lot of “darker marks”. This is caused by warpage of the friction surface.

MIDDLE PIC – Cut #2 – The second picture shows the high majority of the low spot from the first picture has disappeared but if you look closely to the top of the picture, you can still see a thin darker line.

RIGHT PIC – Cut #3 – now the entire friction surface I uniformed and we have completely machined the warpage out of the rotor that was causing the issue in the first place.

The Video here shows Mike talk about the process also;

The final step is to make sure after the machining process the rotor is still above the minimum thickness required. On this F150, we only removed about 0.6mm off the rotor and it still comfortably fit in the safety regulations recommended. With brakes, safety is clearly the main concern but this is a pretty simple fix and the car is taken on a test drive to make sure the issue has been resolved.
