Sorry but this is important.
My '14 with 42k mi. and a tough life in the midwest where salt is used during ice events, or probable ice events, of if they stocked too much salt this season and it's a cloudy day.... :evil:
I removed the right rear wheel to check on the brake caliper slider pins. I was bored and the weather was perfect.
The brake pads looked brand new, the way most EV's would probably be at this mileage.
But, one of the sliders was rusted solid to the caliper carrier.
I pulled back the boot and sprayed some penetrant on the pin and waited. No luck. I could twist it slightly using a lot of force.
I then pulled the boot off and heated the carrier at the stuck pin and with some help was able to twist and hammer the pin out eventually.
I cleaned the pin with a high speed scotch brite pad and cleaned out the bore the best I could.
Then I used the blue 'caliper grease' that comes in single serving packets at the auto parts store and gooped up both cleaned out bores and pins, a lot.
Then remounted the caliper.
THE MORAL:
These cars are mostly Maintenance Free , but this is an important preventative maintenance item that should be performed every few years, even in dry climates.
All in all, it can be a quick job if you don't have to deal with a rusted solid slider. And not too dirty! Wear rubbers!
The brake calipers can be slid up a little to clear the removal of the slider pins.
There is a funny noise dampening device on the top pin bolt on the rear wheels. If you have a thin enough wrench those could be left on the bolt, or there are 13mm flats on the dampener to remove them.
It looks like they should be locktited back on.
So now I know what I'll be doing next Saturday.... :|
