Changing front brake pads - question

ArizonaKev · 09-14-2010, 07:27 PM

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:

Remove the master cylinder cap and open the bleeder before you push the piston in. As you push in the piston, some brake fluid will come out of the bleeder. Don't get it on anything, as it removes paint immediately. You probably won't need the c-clamp. When the piston is all the way in, close the bleeder. Install the pads and top up the reservoir. Makes life much easier. If done correctly, you won't need to bleed the brakes afterward.

Thanks Sarris - that sounds spot on, and I think I will do it the way you suggested. It sounds like it will be a good way to avoid getting air in the lines too, which is always a plus. Appreciate the info man. As we say here in the southwest, muchos gracias!

Just another example of one of the good ole boys again being disrespectful to a relative newb. (Joke, if you didn't know). :poke2: :neener:

We have to qualify and explain all these things now to be PC. :??:

I pushed the piston in without opening the master cylinder or opening the bleeder valve. What damage did I do?

Most likely you didn't damage anything. It's just a harder push. The bleeder is more for changing brake fluid.

At hardware stores they sell different sizes of small diameter plastic hose which is perfect for bleeding the brake fluid without getting it on the bike.
