Bleeding issues

i havent started a thread, but i can get some pictures up if youd like. im sure youll like to see the before and after of the brake rebuild, judging by whats in the reservoir, its going to be a nice transformation!
 
heres what was under the piston, felt nice to see it clean! i can only attatch one pic at a time, but i have to buy a new caliper axle, the one with o-rings was chewed up really bad, like someone took a chisel to it. the piston is perfect, no rust marks or scoring. now i just have to wait for the new seals:cool: i started taking the front MC apart today, but ill have to wait until i pick up a set of circle clip pliers. one thing i noticed was the dust seal is ripped. should i replace it? the only reason i ask is i would have to buy a new piston set just for the boot.
 
Thats the greasy slimed up brake fluid i was telling you about..and was the groove for the oring all crusty? You gotta get all that stuff out of the system..good start and glad your doing it...
 
it definitely wasn't clean, im not sure how old the fluid was but it stained the reservoir to where it wont come off, so im sure it was there for quite some time. i am glad i am doing it as well, when i saw how bad the fluid was in the caliper, i knew that this was beyond necessary to rebuild
 
Youll be glad too should you ever really have to get down on them in an emergency..and we suspect youre gonna get new lines too????
 
thats my logic as well, as im sure there will be a time when i need them in a hurry. sure thing, new SS braided lines are on the way, along with new pads so the entire front end will be completely rebuilt with no loose ends to worry about. the ones on there before were glazed and had some solid grooves in them. the rotors have some grooves too but i dont think it will be a problem as the brakes worked fine before hand.
 
Frt rotor can be resurfaced..as long as they dont get below the manual minimum specs.. The new pads will have to wear themsleves in so dont be alarmed by some squeekind and scrapping sounds for a bit.
 
what do you think about taking a sheet of fine emery cloth to the rotors to get residue from the old pads? its like ill be riding a new bike;)
 
Brake cleaner and a green dish scrubbie is what i do..dont think emery cloth would hurt either..Let other chime in on emery cloth issue though.
 
I use a fine (220) wet or dry sandpaper lubricated with copious amounts of brake cleaner. I wear gloves also because that stuff is not good for you. Also, you will want to cross-hatch it across the disc, not circular with the disc.
 
well i got the new seal and boot on the caliper, and my ss line came in the mail today. now i just have to wait for new pads, and while im waiting for the mailman i made another order. new rubber and pads for the rear caliper. this is moving along pretty slow but when all the parts are here it will be done in a day. now the only thing i have left to do in the way of brakes is the rear lines. i'd like to replace those with SS as well, but im not sure as to what kind of fittings i will need to go from the top of the MC to the hardline on the swingarm. ill figure it out though and post some pictures when i get the front caliper mounted with that shiny new line:D

FYI. There is a break-in procedure for the brake pads and rotors, since they are so hard. I haven't done it myself, perhaps someone can post up the link?

You're coming right along! Don't get discouraged in the beginning. Lots of things up front to get it safe and reliable, then it slows to a trickle based on how much "restoration" you want to do ;)

i saw the procedure somewhere on this forum for breaking new pads in. the wonders of the search function lol. well my goal is to get the bike up the the safety and performance standard it was 30 years if not better, so cosmetically its no gem. but a dented gas tank wont lock up and send me into a ditch:D in due time though
 
just an update, i got my pads today, so i went to Advance Auto and picked up a tube of Sil Glyde Caliper Grease. Any opinions on this brand, or any problems you have heard with it? i just want to make sure im getting the right grease
