A little brake maintenance
When I had my rear wheel off for a new tire last September I noticed that one of the caliper seals was visible and would need to be replaced whenever it was pad time. There was a little bit of meat left of the pads so I put it back together and went ahead and ordered seals so I could do it all when the time came. Last night my new pads were waiting for me when I got home. I knew the rear seals were bad and I had limited time since Wednesday is a church night so I decided to start on the rear, being only one caliper.
The caliper came off quite easily. The seal still looked terrible but the pads were absolutely shot! I try to use my rear brakes along with the front all the time, so I use it more than a lot of people, but not enough to do this kind of damage. I believe the pistons were sticking and thus causing the rear to drag a little, thus causing more damage. This was validated by the fact that I could neither easily remove or push in the pistons by hand. To move them at all I had to use a socket and a hammer and give them a tap! I was able to get the pistons out, old seals removed, everything cleaned up, new seals installed, pistons re-installed, new pads installed, and caliper remounted before church.When I got back I bled the brakes and you can see the old fluid was fairly ugly. I suppose I could have stayed up late and done the front but I just wasn't feeling it, that will be tonight's project.
Anybody interested in the project I've used the following:
Inner Piston Seals - 43049-1092 x6
Outer Piston Seals - 43049-1068 x6
EBC EPFA231HH Pads x2
EBC EPFA229HH Pads x1
2 Bottles of Amsoil DOT 4 brake fluid
I don't think the seals on the front are necessarily bad, but they were cheap enough and they are easy enough to replace. I figure I might as well do it while I'm into it. I chose these pads because I have had wonderful results with the EBC HH pads in the past. These are the new and improved version that is supposed to have even better fade resistance, heat cycling, and noise characteristics. I selected Amsoil fluid because I am an Amsoil dealer and really believe in their products. Both the dry and wet boiling points are sufficiently high to ensure I should never have a problem.
I hope to be able to do the front brakes tonight and it is looking like the weather might actually clear up enough for a ride.
