What is the Brembo brake pad thickness when new? Did a search but didn't come up with anything. I know we had to have talked about this in past.

Doing 20k service. Pads on Limited. Look OK but not sure how much pad a new set has.  All three sets look to be about 1/16 of inch pad left. This would be about .0626. Manual says run until .016.

I know there is some left on these. Question is could someone measure a new set so I have a reference?

Thanks

Also what milage are you seeing on these?
How about original front tire? On second rear but front still look ok.

New pads are 0.150" thick. The pads have wear lines in them. When you can't see the line, you are at the limit. I've never let them get that low though.

I see the lines but mine look like backing would hit rotor before lines would be gone. Thanks for reply. Looks like I am little past half then.

The bottom of the line is just above the wear limit specified in the manual.

Never seen the line referred to, but the minimum thickness per HD is 0.016" or 0.4 mm.  Thats thin!  I replace mine before they get to that point.

My first set on my 09 went to 44k, had about half left at tire change at 34k but at 44k I just caught them in time, in fact one corner had gone to metal, a spot about a quarter the size of a pencil eraser on the outer edge. Either I used them a little harder that last 10k or they wear a little faster as they get thinner, I am thinking the latter. Fronts still got lines in them at 53k

Thanks. I read the manual about the wear indicator lines. Just looking at mine they appear to be all the way to backing plate. I guess they are not but I will change them out before the lines are gone too. Going to give them 10k more hopefully.
I have to say with the longer lasting tires and brakes , plus longer intervals on maintanence, standard sizing o rings on drains, and the throttle by wire so less cables to lube, prices should have went down on service for everyone. Do it yourself or even shop time (looking at the board in the service dept I see that isn't true)

Update on brakes- Never changed pads last year. Got 26,000 on bike now and about 7k since last time posted. Pulled calipers to change both tires and thought I would need some brakes now too.

Fronts .071 (1.81mm) Rear .125 (3.18mm) 
So front is about half worn if new are .150. Rears even better. I use front 100 percent of time and rear less than 50 so it makes sense.

Thinking I will ride another season and see what I get. Even at .071 it looks thin but lines are strong, wear is even on pad and still much higher than the .016.
Tires got a little room for more wear in middle, ton on side but got a good cupping started. Profile is not smooth round but more of a center then two angles off side. Front is original at 26k and rear is probably about 13k. Still some room to wear indicators on center probably 2/16 total depth (indicators sit at 1/16). Way more milage than old style but they are expensive.
Opinions welcome.

 

Certainly the rear tire has been changed once already?

Yes

I was wondering the same thing, I changed my rear pads between 15k-16k.

Any problem with bleeding their rear calipers, being as the bleed valve is on the bottom side of the caliper?
Did not understand this design feature ... should have been at the top as all the others are.

My limited has anti lock so I can't bleed at home. Dealer needs to open valves in anti lock with some scanner of sorts. Need to take in to dealer have fluid changed according to what people have said. Every two years was being told. Don't know where this info came from, but fluid gets contaminated with moisture was reason. Being system is closed, never opened due to window view glass on both master cylinders, guess a tiny amount enters some how but I sure don't know.?

Decided to change fronts. When I cleaned everything up I pulled the pad pins to clean there too. Once pads were out I saw the edge of one pad was down to .048, so about 2/3 gone. Worried about that edge wearing faster and don't want problems on a trip next year. New (2 sets) cost me around $100. So 3 years and 26k isn't bad, dealer says 1 hour labor ($72) to change fluid. Are people really flushing them out every two years? dealer recommending it to people bringing them in?

Rears are original pads, but I am a front brake guy. From the safety course. In fact I remind myself at times to add some rear. Those linked brakes will be good for me on next upgrade bike.
So 26,000, one front tire and brakes, two rear tires and original brakes.

Anybody else having trouble bleeding Brembo brakes on the rear, with the bleed valve on the bottom of the caliper?

All of them I've ever seen have been at the very top.  Heres the one on my 2014.  Never seen a bleeder on the bottom of a caliper unless something was installed incorrectly.

Look at the brembo rear 7007 caliper...its on the bottom.
I have to take it off and hold it upside down(putting bleed up) to bleed all the air out.

Changing fluid every 2 years is a good idea. Just take a look at the old fluid when it comes out and compare it to new. You won't think it was a waste of time.

fatboy that's what you get when you kluge a caliper onto a bracket for use on something for which it was never designed.

Not sure what you mean, says
"For 00-05 FXST/ 00-07 FLST (except 07 FLSTF)"
Brembo caliper model #7007
Bracket comes with the caliper, you're looking at the wrong pic.

Doesn't matter what I'm looking at, the QTM Guys (ex Brembo Engineers) have taken various model Brembo Calipers, both Front (L&R) and Rear, that are predominantly used on European/Performance Bikes (BMW, Aprilla, Ducati, etc) and made brackets so that these Calipers can be fitted up to American V-Twins which includes HD's.

The only purpose built Brembo Caliper for the rear of a HD (excluding the VRods) is pictured in the post by harleyjt.

Yea, but mines an 02 and I need a 2 piece smaller caliper.
Using it on a 4" x 16" rim and tired on grinding the back of my caliper
off to get it in and out of the wheel.

Then take it off when you need to bleed it.  I upgraded (!) the brakes on my cage, to get them to fit I've had to install the L on the Right side and the R on the Left side which means the bleed nipples are at the bottom of the caliper     so when fluid change time comes around or they need bleeding I have to take them off to get it done.   Such is life, some play golf.

That's where I'm at...Thanks

Back on subject, more concerned with stock set ups and what the touring guys were getting out of the pads vs tires.

Measured new set at .140
