A car's rear windshield wiper rotates 135 degrees. The wiper mechanism has a total length of 23 inches and wipes the windshield over a distance of 14 inches. Find the area covered by the wiper. Convert 135° to radians: θ 135 * (π/180) radians 3π/4 radians Arc radius 14 inches Area of a sector of a circle (1/2) * r^2 * θ A_23 (1/2) * (23^2) * (3pi/4) 15625pi/72 ≈ 217pi in^2 A_11 (1/2)(11^2)(25pi/36) 3025pi/72 ≈ 42pi in^2 A 217pi - 42pi 175pi in^2
If done correctly no harm at all. But keep in mind that brakes are cheaper to replace than engines.
You do not buy brake pads to preserve them, they are consumables. There is no consolation when pulling your bike out of ditch to know that the brake pads are pristine. Engine braking is a relatively simple procedure and can be used to assist braking in normal riding, some engines work better than others, I have a 600cc single with high compression, sometimes it can be like dropping an anchor, especially compared with my 600cc inline 4. btw that seems a hell of a lot for a set of brake pads, if you have bought them for all three discs be aware they do take some time to bed in and work at their optimum, at least 50 miles of normal regular use.

doesnt hurt the bike at all. I do it a lot my OLD panheads since they have mechanical drum brakes LOL
