I just finished installing chrome sliders, hogpro 21" front wheel, HH 6 piston caliper with Lyndall pads and matching 13" hogpro rotor. Along with that I installed the Arlen Ness 1 1/2 shorter dampeners. Here's the problems. When I put on brakes, light, hard it doesnt really matter, I get a slight pull to the right, very consistent. The lever is initially firm, much firmer than stock which led me to believe I would have great brakes after I got them broken in. I did some riding this afternoon to try to break everything in to see if the pull went away. Well, after two cycles of braking hard from 80 down to 20, I noticed a wobble in the front end, looked down and saw that the rotor was wobbling violently. I checked the front brakes only to confirm that I had no brakes. The rotor had pushed the pads back into the caliper. I come to a stop to get off and check everything. Do a visual of the rotor and it looks fine, no warping. I get back on the bike and the brakes are fine again. I do two more stops and this happens again. It happened all the way to my destination and back home. So, to conclude. The front end pulls to the right when braking but doesnt cause the bike to turn and the rotor are warping prematurely then straightening out after cooling off. I plan to replace the Lyndall pads with the HH pads that came with the caliper tomorrow to see what happens then call HogPro on Monday. Has anyone ever experienced this, or have any insight to what might be causing my problems. I'm using DOT 5 fluid, I flushed the reservoir and master cylinder pretty good prior to installing the caliper and bleeding brakes. I dont feel that this could be the cause.

Did you align the fork legs properly as you tightened the triple tree bolts?
Are the dampeners you speak of replacement (shorter) damper tubes?
The cables hanging up upon braking?

Hmmmm...

I'm also thinking that if your brakes are bled properly and you're getting what you're getting, I'm guessing the caliper doesn't have the right 'offset' to the leg. That is, when the caliper bolts are tightened the rotor hangs up in the caliper/pad to one side or the other? Spacers wrong on the wheel can do this. or you might need to shim the caliper one way or another.
You did change wheels?

There is no one who can tel you what is wrong except the person who has the bike in front of them. I do not think I would have ridden the bike very fast home as you did. There are a few clues to your problems. When you apply the brake, this could be why your bike is turning to the right. But another clue is your caliper, when the brake is applied, the bike should turn to the left (single caliper). Your front end/wheel must be twisting somehow to make your bike turn to the right.

You need to check your caliper alignment in relation to the rotor. your right turning is perplexing as your friction should turn the bike to the left. Maybe the bike being 1 1/2" lowered and the rear not lowered the same 1 1/2" may have something to do with the right turn. Who knows without the bike in front of you. In my opinion I would start by looking at the:

1. front end for being assembled correctly with proper tolerances.
2. wheel attachment and alignment in relation to the caliper/rotor
3. axle/spacer fitment & movement. Your spacers must be cut to center your caliper/rotor than your forks to to not be pinched but hang without resistance (a common mistake).
4. wheel bearings, and wheel tolerances (unlikely but possible).
5. Unlikely problem there is a problem with the rotor unless .
6. I doubt if there is a problem with the pads. HH uses a privately branded pair of sintered Ferodo pads. The Lyndall coating already on the rotor must be removed by hone than a new coating transfered from the Ferodo's. Highly unlikely it is the pads.

without the bike in front you the above is just a guess at best. Good luck.

 

1. I'm pretty sure the forks are installed correctly
2. & 3 New wheel uses stock spacers which I know are put on right, short one on the right, long on left with notches facing inward. Axle is Adjure flush mount installed per directions on website.
4. wheel bearings were installed by hogpro before they arrived as well as rotor.
5. I think it may be the rotor, I cant believe it would get hot enough to warp after two stops.
6. I was doubting that its the pads also, but checking every possibility.

 

This is only what if answers. As said before, without the bike you can not....
By the way I was typing for 45 min and going over all possibilities last night when my friend Carry (Comfortably Numb) came to a conclusion. I had my message screen open while typing & did not realize he had answered.

• I do not think it is HH calipers as they are all good quality
• I do think it is caliper/rotor alignment
• I do think it is something to do with the wheel and bearings.
• Make sure the rotor is centered inside and in the center of the calipers, a must.
• At this point the instructions do not work so look at other alternatives.
• Put your bike on a table, jack it up so the front wheel is off the ground, take the pads out, and spin the wheel.
• Keep in mind the front end.
• Keep in mind that the forks should not draw in due to smaller length spacers (common mistake). This should be a slip fit.
