vangonebuy Report post Posted March 9, 2018 63K+ miles and the rear brake pads looked very thin...Rotors were grooved also on all 4 wheels.But the front pads were barely worn at all. Prices on rear replacement pads weren't bad. $64But the parts store rotors price were high. $72 a rotor and out of stock.Since the rotor didn't look too worn.. I thought cutting them would be the way to go. Interesting with the new Electric E Brakes.There is a service mode procedure to wind the E tension back into the caliber.Reverse procedure with the Brake Pedal to undo the service mode.Look it up on You tube for step by step. Disassembly was e z.But noticed many pit holes in the back side of the rotor.Changing rotor would be mandatory now.Called a 2nd parts store. Same chain and part #...... $34 a rotor..... SOLD. Observations:Wire tension clips on caliber is a PITA to put back in. Not awful though.And there is no squealing clip on the original pads to let you know they are worn. Since the rear rotors were so pitted. I will probably do the fronts soon. Pads look perfect, But they will go too.Front rotors are lightly grooved also and I'm guessing they are pitted also on the inside. Maybe 1 hour total.

Vangonebuy, I was trying to find a past thread where I remember it being discussed about the front rotor/pads having far less wear than the read rotor/pads. I use to believe that the front brakes typically wear faster than the rears largely because of the physics involved (braking shifts weight to the front tires and the rear tires become less loaded) and from what I was taught in my auto shop classes many decades ago. Was that just incorrect old school thinking on my part, or has there been a design change in modern cars that gives a braking bias to the rears, or is this a peculiarity of our hybrids? Maybe Waldo could help explain this if you don't know. Also wondering if the pitting and grooving is peculiar to our hybrids? Would periodically braking hard reduce the pitting and grooving? 1 vangonebuy reacted to this Quote Share this post Link to post Share on other sites
lolder Report post Posted March 10, 2018 (edited) Since all the regen is done on the front wheels, the system balances it for stability by applying rear mechanical brakes unless you are very light on the braking. Brake score may be the gauge and 100% may mean no mechanical braking. Edited March 10, 2018 by lolder 2 vangonebuy and Texasota reacted to this Quote Share this post Link to post Share on other sites
