So I took the 4 bolts off the caliper and the one off the brake arm thingy. I am getting ready to apply the high Temp RTV stuff to the back side of the pads to hopefully stop the screaming brake issue.
Anyway, now that I have the caliper in two I noticed that there is a port hole on the inside of each calipers. The inboard one has an "O" ring in it. I have never seen calipers this way but can I assume I have opened the system to air now? I guess brake fluid flows from one side to the other when they are bolted together, therby activating the pistons. I noticed some brake fluid weeping around the area after I took it apart.
Does the "O" ring go bad? I think it may have had a leak before I bought it from the previous owner. If so can I get the "O" ring at a good harware store or does it have to be a Suzuki replacment part? I guess this also means I have to bleed the system, right?
How do you do that? I don't have a manual yet.
Thanks for any help! :D
You didn't need to remove the 2 bolts that hold the caliper together to get to the pads. If I remember right you don't need to remove any bolts at all, just pull 2 pins. Doesn't really matter now, though.
You should replace the o-rings since you have it apart. Old o-rings don't always seal up like you would hope, especially if the bike is more than a couple years old. My 90 caliper o-rings were literally as hard as a rock and deformed. The genuine suzuki oring costs a couple bucks.
If you go to the hardware store for an o-ring you might be asking for trouble. O-rings come in lots of different materials and some might not react well to brake fluid.
Yes, you'll have to rebleed the system.
