Some may apply one or more pieces of latex rubber, called prosthesis, shaped like muzzles or ears, to their head with spirit gum.
Say it's a basic brake job on the front end of a vehicle it can be 1.25-2.5 hours on average. Now that's if you replace the pads, rotors, and hardware. You could just slap on pads which may take 30-60 minutes. Now is scheduled ahead of time and the parts are already on hand boom bang not much extra waiting time. But sometimes there is an extra wait time on parts. Other types of vehicles can require a lot more labor hence time to complete the job. Domestic to foreign vehicle brake systems all very a touch to a lot in design and whatnot hence changing the wait time.
