Unfortunately you need to remove the wheels to grease the brakes, but while you have the wheels off, you can replace the straight grease fitting with 45 degree angle fitting and position them so you can grease them with the seat lifted. Check out the pics. I also replaced the fittings on the push arms, (Fig #59) with 90 degree fittings so I can lube them easily at the same time. Just did a 50/100/200 hour service on my machine, much easier since these mods. Bear in mind that there are SAE and Metric thread grease fitting, you want SAE fittings with 1/4"X 28 threaded fittings. My grease gun has a flex hose on it, but I have a metal adapter about 6" long that I use to get onto these fittings.

Just looked at my Tiger Cub and I rotated the brake grease fittings inboard just a little more than these pics show which made access to them easier.
