So, I got some Lyndall Gold+ pads in today (thanks to Al @American Sport Bike!) to replace my worn-out stock pads. My stock pads lasted 10k miles with no pulsing, but *lots* of brake dust.

In reading the back of the package for the new pads it claims "No Break-In Required". This is distinctly different from the last set of Lyndall pads I saw which said to perform 10 hard stops from 20 mph, 10 hard stops from 40 mph and then let the pads cool to ambient temps.

What gives? Is it a new pad formulation, or just lawyers telling Lyndall that they shouldn't encourage customers to be making hard stops? I still plan to bed the new pads in to aid in clearing any crud off my rotors.

According to the Lyndall site:

Z-PLUS

Our Z-Plus compound is a softened version of the gold compound and does not require break-in. It is excellent for general purpose riding and offers a high coefficient of friction. This is the most rotor friendly pad in the industry. It produces no dust, no rotor wear, and no noise. The service life generally averages about 18,000 miles.

GOLD

Derived from Formula Atlantic and Indy Light open wheel car racing, this friction material is a proprietary blend of Carbon- Kevlar and trace iron that excels in extreme environments. The Gold pad requires break-in and generally averages about 7,000 to 10,000 miles.



Did you get the Z-PLUS pads ? The site showed that they were not available for the Uly, just the tubers. I don't know if that is current info though.
I just ordered the gold pads from American Sport Bike today; I'll see what shows up.

I had a set on my ULY and did the old style of break-in with the 20 hard stops...The rotor gets extremely hot which could lead to a warped rotor, maybe this is why it has been eliminated.

I ordered Al's part number 9060. He lists it as Lyndall Gold Carbon Kevlar.

The Lyndall part number on the package is 7228 Gold+. Lyndall does not list a Z-Plus pad for the XB Buells and my pads are painted gold and in the same packing as the old style Gold pads. I found it unusual that mine were labeled as Gold+ - I've seen no mention of it on American Sport Bike or Lyndall's site.

Same ones I ordered today.
Might be worth a call to Al to see if the Gold+ is something new.

Adrian,

The Z-Plus are not available.

Gold require the break-in.

The rotor getting hot is part of the break-in.

I sent an e-mail to Al last night regarding the Gold+ pads and here's what he had to say:

"The compound has changed, but the characteristics are still very
similar. Paul Lyndall tells me that they don't need the same break in, but
personally, I'd still do it. The enemy of a new brake pad would be lots of
heat with no pressure, i.e., what you'd get from lightly dragging the
brake. The surface of the pad would glaze before it adopted the rotor
grooving, and it might not ever get the same level of groove match. I
suspect that the new material is less susceptible to glazing, thus the
removal of the break in procedure. But I still think heat and pressure will
accelerate the marriage of the pad to the rotor.

Al"

And on that note, I've been running the Gold Plus pads for the past few thousand miles. They are very characteristically Lyndall, in that they have a very progressive, linear feel to them, and don't have the almost digital initial bite that the sintered pads do. I used them at one track day, and never experienced fade. But I'm hardly god's gift to road racing, a faster rider may have a different experience, I dunno. They have enough bite to stoppie, but it likely requires more hand pressure than a sintered HH pad to do it. I personally like the "harder you squeeze, harder you stop" feel, and you don't need to be Hercules to lock up the front end.

Note: I AM running a Nissin Radial Master on my Uly that I did the testing with, which of itself offers better feel. I haven't run the Gold+ with the stock MC yet.

I've heard of a few folks taking the original LRB Gold brake in procedure to extremes, bluing the rotor in the process. 10 moderately hard stops from 20mph, followed by 10 moderately hard stops from 40mph, should not do this. I suspect those folks that blued the rotor interpreted "hard" different than I. It used to say 10 .45G stops, but no one knew what that meant. A .45 G stop is about halfway to a stoppie, I think.

I bedded in my Gold+ pads the same way as the original golds. Maybe I didn't need to, but it seemed to work well. The Gold+ pads are a replacement for the golds, not a new pad to run side by side with them in the line up. I'll update the website to reflect the change.

I did the 20 stop break-in and I think it was maybe a little bit too much. I'm pretty sure I was nowhere near stoppie territory, but did do some nice progressive, hard brake applications like I would do on the street if I needed to make an emergency stop. I got some fade on the last stop and the rotors were pretty damned hot - just a hint of bluing, but they look like what little deposit was on them is now gone. If I had to do it again, I'd probably stop after 7 or so 40mph applications.

The Gold+ pads definitely feel different that the stock Nissin pads. I think they have much less initial bite, but respond much more predictably to increased lever pressure than the stockers. And they go "ZZZZZZZZZZZZ", which is kinda cool.
