Again, say what? Why would I need to bleed my brakes on a pad and rotor replacement?
I've never needed to bleed my brakes when replacing pads/shoes. If done properly, the system stays closed. If replacing or repairing calipers, then that's a different matter.
As for oil changes, I do them earlier than most, only because I don't drive much anymore (21,000 miles in five years), and will never hit the recommended mileage interval.
You don't NEED or HAVE TO bleed your brakes if you don't want to. It's your vehicle to treat however you choose. And I don't agree with some of the overly short recommended intervals such as BMW on a 2 year schedule. And others have their own intervals as well. I typically use 5 years max whether it coincides with replacing brakes or not. Sooner if it's convenient along with brakes.
All that aside, it's called preventive maintenance and has it's benefits for those of us that want our vehicles to last a long time and be reliable.
Regardless of your success in not bleeding or flushing brakes, here's a few points to consider:
1) Brake reservoirs are vented so a vacuum doesn't develop as the fluid level drops, so air does contact the fluid.
2) The calipers and wheel cylinders are the lowest point in the system where the (heavier than brake fluid) moisture and particles from seal wear accumulates. For those of us that actually bleed brakes, at least some of us have seen the nasty black fluid that comes out.
3) That moisture can cause corrosion to those close tolerance hydraulic valves in the ABS system valve block. In addition to ABS malfunctions they are expensive to replace, even as a reman unit. Some of those also have their own separate bleeder screw for a reason.
4) Caliper pistons. A caliper piston can rust from the inside and 'hang up'. The only thing retracting that piston back away from the pads is the piston seal returning to it's normal shape. It deforms under brake pressure as the piston extends and retracts the piston when it springs back to it's original shape. Think, when's the last time you've seen a retract spring inside a caliper?
5) Bleeding ensures that the bleeder screw has been periodically opened so that it is less likely to twist off from being corroded shut when trying to open for the first time in many years. Road salt has it's effect on this. I heard they salt the roads in Canada.
While on the subject of brakes, how about brake hoses. Inspecting those is part of performing a proper brake job. Looking for cracks and leakage. Road salt and hot climates can dry these out too. Those I'll change out if they are getting too stiff even if not leaking . Usually around the 11-12 year mark. Don't want to wait for the leak. I like a well functioning brake system. Stopping the car is more important than moving it.
