Changing front brake pads - question

[ArizonaKev]

Ok, so I am going to be checking my front brake pads and am thinking they are going to need to be changed soon. I have replaced several sets on cars, and pretty much know all the ins and outs of it - biggest thing (for me) being HAVE A C-CLAMP. I've got one, and I read through the part in the service manual for the GZ about it.

However, there was one thing I noticed that is either missing, or different from cars : I didn't see any mention to take the lid off the master cylinder when compressing the piston in the caliper, which is something I have always done - and believed was supposed to be done - when changing the pads on cars to avoid putting pressure on the system when the piston is compressed.

So my question is - do I need to do that when changing the pads on the GZ or not? If not, I am curious why it would be different than on cars...

Thanks all :2tup:
