Supporting Member texscottyd Posted December 21, 2017 Supporting Member Share Posted December 21, 2017 @betoney - That’s bizarre. Are the backing plates completely flat and true? It almost looks like they are bent right down that centerline cut in the pads to have such obvious wear clustered in the center of the pads’ friction surfaces. I’ve had pads glaze from overheating, but that’s an entirely different look. Link to comment Share on other sites More sharing options...
pattonme Posted December 21, 2017 Share Posted December 21, 2017 can we get a on-edge picture? Is the pad surface dished? Link to comment Share on other sites More sharing options...

I’ve had pads glaze from overheating, but that’s an entirely different look. When I had the pads out for cleaning, I put them together face to face like they would be contacting the rotor and on the outer edges you could see light through the crack, which would coincide with the wear pattern on the center. The way the pistons contact the pads, I cant imagine how they would be bent inward, the pistons are further out from the centerline. Whats really strange is all 4 pads look like this. When I ride the bike, there is no pulsing or vibration from the brake lever indicating a warped rotor. I can only conclude that like you said, the pads must not be flat. ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...

Is the pad surface dished?Matt, sorry, the bike is already put back together for today. However like I replied to @texscottyd , when I sandwich them together face to face like they are when touching the rotor, I can see a sliver of light shining through on the outer edges. ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...
Premium Member 2and3cylinders Posted December 21, 2017 Premium Member Share Posted December 21, 2017 Besides braided lines, as the pads are apparently not flat and must be replaced anyway, do yourself a favor and try some Vesrah RJL pads, as the OEM pads are GG not HH+. More pricey than EBC but IMO worth it. I presume you clean your rotors with 3M Skotchbrite "red" pads with brake cleaner but instead of CRC brake cleaner (IMO the best chlorinated solvent), a much less noxious alternative is good old 91% isopropyl alcohol straight out of the Walgreens'/CVS square bottle, which will accept a standard atomizing sprayer. Just be sure to liquid wax your wheels before and after when using either fluid. Link to comment Share on other sites More sharing options...

Yes, the pads appear to be faulty, I will get them replaced soon. I'm still chasing the elusive "soft lever" gremlin. Concerning the braided lines, I was at the local shop this morning talking to them about this very issue and the mechanic said removing the factory hard lines is a b!tch and very time consuming. ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...
pattonme Posted December 22, 2017 Share Posted December 22, 2017 pads that are 'rocking' on a high spot can easily result in a lever that won't lock up tight. Link to comment Share on other sites More sharing options...

I want the firm lever feel back. ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...
skipperT Posted December 22, 2017 Share Posted December 22, 2017 Also make sure they are installed correctly. Sometimes the anti rattle clips have “guide” tabs on them for the top of the pads. This might have been what damaged the oe pads in the first place. Skip. Link to comment Share on other sites More sharing options...

Premium Member keithu Posted December 22, 2017 Premium Member Share Posted December 22, 2017 Did you bleed at the ABS unit itself? Is there a special procedure for this? I haven't replaced my brake lines but I did recently flush my brake fluid and the ABS didn't require anything special. I have stock lines, MC, and pads and I was able to stoppie on the post-flush test ride (as much stoppie as the ABS will allow, anyway). Link to comment Share on other sites More sharing options...

Are you talking about the copper plate on top where the pin goes through? I dont think it is possible to install that backward or upside down or any other orientation. ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...
docsimple Posted December 22, 2017 Share Posted December 22, 2017 yes I bled the the ABS. You have to when replacing lines as it needs to be emptied or you will have a big nasty mess. Getting the ABS refilled, without bubbles... well, lets just say I bought three of the large size brake fluid containers and have less than 1 left. I ended up getting a bleeder that you hook to a compressor line. I kept running fluid until the bubbles were gone and then manually did a little more. It's a bear but should be a one time deal for the life of bike (for me anyway). I still have not done the back yet because of this 2015 Red FJ 09 2013 WR250R - little boy blue - sold 2012 DL650 V Strom - sold 2007 FZ6 - sold 1986 FJ600 - sold Link to comment Share on other sites More sharing options...

I still have not done the back yet because of this I found a very interesting article about Installing a banjo bolt with speed bleeder on ABS unit I am not sure this part would fit the ABS unit on the FJ without extensive modification with a Dremel. Regardless, I thought it was a clever idea to resolve the issue. ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...
Premium Member keithu Posted December 23, 2017 Premium Member Share Posted December 23, 2017 This discussion has me wondering... When I flushed my brake fluid it was pretty straightforward. I didn't have to do anything special with the ABS unit. I also didn't use a huge amount of fluid, 12-16 oz at the most. Is there a large volume of brake fluid in the ABS module that I didn't flush?
