First pic is your Switch that activates your reverse lights,oil leak pic i'd suggest a new rocker cover gasket...easy to change and cheap,Brake pads easy to change, just 2 bolts holding the calipers on...shouldn't be too difficult,just remember to copper grease the back of the pads and caliper area so they don't squeek.to make it more punchy how bout an filer element from KnN or summit? maybe a service i.e leads and plug change too,injector cleaner also? just some ideas
