So I just did my brakes following the DIYs & I was wondering, how do you grease the caliper pins? When I changed out the pads I did grease the pads but I noticed that the caliper pins were a little sticky on one side. I was also wondering, are there any other grease points? where? how? what kind of grease? and I took this picture off Web's DIY but is this the grease nipple for the caliper pins?
