Replacing the brake pads is quite a simple task.
After jacking the vehicle up, remove the wheel
There are two bolts holding the caliper to the wheel arm thingy.
once these are off the caliper should move freely away from the rotor.
The pads slide in and out quite easily.
Remove old pads and check for uneven wear, and any scraping on the rotor
If the rotor is damaged get skimmed or replace!
Make sure you keep the metal backing plates for the pads! and remember which side they go on.
The caliper piston on the front can be pushed back in with a simple caliper depressor, but the rear ones require to be turned as they go in. you can borrow/hire the tools from most mechanics, or some auto shops.(before you depress the piston remove the cap from the brake fluid reservoir as you will get back- flow)
When puting in the new pads, you should feel a light click as it falls into place
Whilst you have the calipers off you might want to give the sliding rods a quick bit of grease - the rods that the calipers 'float' along
If one of these has been sticking it can be the cause of uneven wear.
Replace the calipers in reverse of the way we took them off and your new pads are a go-go.
Replace the reservoir cap and top up if neccessary.
Just too wear them in, I like to gently pump the brake a few times while keeping one foot gently on the accelerator.
Then get up to speed ~60mph then jump on the anchors for a moment - this also helps to remove any lips on the edge of the rotor!
Hope this helps y'all!!!
