I tried avoiding $800 quoted price from dealer to fix brake pads.

Bought after market pads and had a friend attempt.

Once they took the tire off, tried removing caliper, after unscrewing and giving it a couple knocks, it came off and started leaking!

He put it back immediately, and we replaced the tire as is (without replacing brake pads)

now the car is beeping, abs and esp lights on and braking feels dead in that side.

please help...
