One Break Pad Badly Warren

[WRB08]

I was looking over my 08 FJR getting for a long trip and found one break pad badly warren, it was on the left caliper,inside rear, I have 34k miles and all the rest of the pads look great. any body have an idea why just one ware like that. Second question is it ok to just change one set for the trip and do the rest when I get home. Thanks for any help.

Replace all of them, one worn brake pad indicates the caliper is dirty and not releasing on that one side. Brake cleaner and gently scrub the grunge off the piston boots The keeper pins should be sanded down and greased with high temp brake grease to assist them in returning to an open state.

Parts Shark is in IN and maybe close. That is a lot of miles on pads, one reason I use OEM for replacement. Bleed with DOT 4 and ride on.

Other experts will chime in.

You can replace just the one pad...but who's Warren?

He's a break dancer.

They tend to wear unevenly but if it is extreme, you may need to clean up the pistons and the slider (as Hotboot mentioned). I usually swap inside-outside pads for each piston at half life to get more wear out of them. While I think you should clean up both of the calipers and all the pistons, I don't think there is a need to replace all of the pads. I would only replace ones that are worn to well below half. It's a good idea to have a good look at the pads regularly - especially whenever you have the wheels off. When I change pads, I extend the pistons most of the way out (don't go too far!) and wipe the outsides with a soft cloth. You don't want to push dirt past the seals when you push them back in. Personally, I am just as happy with the EBC HH sintered pads as with the OEM. About half the cost and just as effective in stopping with maybe slightly less lifetime. I have been using them for the last 120,000 miles without any issues.

Was the pad that was worn the most on the lower part of the right caliper? If so, this one is actuated only by the rear brake pedal. This means that you are using far more rear brake than front and/or the rear brake pivot is gummed up and sticking. Front brakes are far more effective in stopping your bike. I normally go through almost two sets of front pads for a set of rear pads.

He has several good videos on brake maintenance.

May be time for front caliper seals. If the piston can't retract properly, it keeps pressure on the pad, which obviously wears it faster than "loose" pads.

I ddin't know 08s had duel caliper rears. You learn something new every day.

 

[NMRoadRunner]

If one is "Warren", what do you call the others?

No reference was made to dual calipers on the rear. I mentioned that the lower right piston pair (on the front wheel of a GenII) was activated only by the rear brake pedal - part of the linked braking system. The other three piston pairs are activated by the hand lever.

In re-reading the original post, I see that the issue was with one of the pads on the left side so nothing to do with the linked rear. Dirty or bad seal or slider (pin) crudded up so piston doesn't retract properly.

Warren? I evicted him for not paying rent.

The other ones are Ted and Eddy.

Thanks to every body that responded to my post, I learned so much I love you all, God bless each of you, ride safe.

I like the video, but good grief, a cheap disposable pair of nitrile gloves would save his kidneys from that brake cleaner.

In my younger, dumber days I would use MEK to clean B1/2 off my fingers, got Skydrol on my skin and had a rust chip drilled out of one cornea. Glad I don't do that stupid shit anymore.

Ask the one on the left. The right head's a damn liar.
