less brake fluid with SS lines?

[jmd2914]

im running SS lines should i use less brake fluid? brakes are groaning...tryin to find out why

[elskipador]

you may use less fluid, depending on the ID of the SS lines vs. stock, but the fluid level should be the same.

[jmd2914]

alright, any other causes of groaning brakes when lightly applied at about 5 mph?

[Sane_Man]

Did you follow the directions and scrub them in?

[ST Guy]

New pads? How many miles on them? What brand and model pads? Some pads just make noises. Did you use the backing plates behind the pads? Did you use any of the high temp grease on the back of the pads?

[jmd2914]

dont think i used any high temp grease. none came with them, theyre ebc pads, got them at fairfield cycle center. they started groaning about ten miles after i put them on. what did you mean by scrub them in? the lines were on the bike when i bought it, the groaning started when i changed the pads and flushed the fluid and started using redline race fluid. dot 4 or 5 i think

[jmd2914]

and i didnt see any seperate backing plates other than the one connected to the actual contact patch on the pad

[ST Guy]

Well, it sounds like the pads are the source of you groaning. Scrubbing them in (or bedding them in) is simply wearing them enough so that they conform to the tiny undulations or grooves that are circumferentially arranged around the rotor surface. Unless they're brand new, rotors always have some unevenness. And it takes a few miles until the pads can wear down sufficiently to conform to the contour in the surface of the rotors. During this period, it's important not to brake too hard or too often because until you have full contact between the rotor and the pad, a much smaller surface area of the pad is in actual contact with the rotor and it's much easier to overheat and glaze the pads until you do have full contact. How long this takes depends upon the condition of your rotors. If after the pads are fully seated, you still have the groaning, then it may be just the nature of the pads, dirty rotors (which can often be cleaned), or maybe some of the special grease on the back of the pads will cure it. I'd try cleaning the rotors first.

Curing the resins in the pads through heat-cycling is also part of the break-in process. :)

[jmd2914]

well theyre still groaning and ive gone around two hundred miles. so i think cleaning my rotors would be the next step? can i just put some brake clean on a cloth and use that?

[elskipador]

did you get the HH pads from ebc? if so the noise will never go away.

[nickler]

I had HH EBC pads on the 636 and they whistled the whole time. I just went back to stock for the street.

[jmd2914]

they are ebc pads, dunno if they are HH pads though. i cant recall. they stop me just fine they just groan. i just dont want the brakes to lock up on me or anything like that.
