I thought I might mix it up a bit in this next post and showcase a little bit of what the students of my Automotive Foundation class have been up. The last four weeks we have been studying brake systems. As the students have learned there is a lot more to doing a proper brake job than just installing new pads or shoes. The brakes on a vehicle are one of the most important safety features, failure of any of these components can lead to dangerous situations.
Installing new pads onto a rotor that is excessively grooved will cause reduced braking and heat dissipation until the flat surface of the new pad seats into the grooves of the old rotor. Not a very safe situation.
Here the job is being done right. He is installing a new set of brake pads on to the freshly machined rotors of his VW Golf. The smooth flat surface that was machined into the rotor creates the perfect finish for his new brake pads to bed into and properly seat.
