Thanks, I set up all the brake cables/housing at once, but can't remember exactly how I routed the front brake. Knock on wood it seems to be functioning well, but I'll pop the front cover off to have a look.

I'm wondering how all the sweat got down inside the rear brake. Maybe traveled down the brake housing from the stem area? Who knows...

So you routed the brake housing from the rear brake all the way to the lever itself without a separation at the steerer tube? The front brake was also an issue for me as the tight bend in the low far config made the front brake always tend to rub on 1 side. It drove me insane until i figured out that i needed to bend the wire in the opposite direction so there was even tension on both calipers. If its working for you I would not touch it hahaha!

Try the brake wedge trick. It might fix this entire issue for you (move the brake wedge up .5-1 inch further up the wire)

Also I know this might be beating a dead horse, but use a towel or 2 always indoors. I have done this and I have had no issues with my bikes other than a replaced fork bearing set, but I think that was due to just how much riding I was doing and some wet races.

Edit: If you have the housing in 1 shot it should be easy to replace the brake cable and seeing if it helps. TBH I would consider doing that or buy an el-cheapo wire (like 4$) and seeing if it does the trick. Shouldnt take more than 10 mins if your taking the entire thing apart anyways and if its in 1 shot, its a quick swap out

Howdy, this is regarding the rear brake on my 2011 speed concept. The brake cover came off. I ordered a new one with bolts, but I have lost the brake booster, as my LBS called it, and cannot find one on the trek website. Can anyone help out here? thanks Bob

Anyone know the spec of the longer 3rd bolt on the speed fin?

Another brake question.....thought I might have brought this up before but I cannot find it here......
For the front brake, anyone else had the issue where the wedge seems to move one brake arm a lot more than the other? I've tried playing with the side adjustment screws, but no matter what I do, I cannot get the arms to both move evenly and with the pads evenly spaced from the rim. If I'm looking at the bike head on, the left arm is mved by the wedge, the right arm doesn't move nearly as much...

Well, beyond frustrated with these brakes now, to the point where I regret buying the frame. Promised myself no more 'integrated' rim brake frames, and I did it anyway, ugghh..

The front brake wedge sits at an angle, and I can't get the arms to move independently with their adjustment screws, and the whole thing kind of binds when I put the cover back on.

The rear brake won't open up on its own anymore. I took the old cable out and put a new one in. The cable, before attaching it to the wedge, glides through like butter. Attach the wedge and put it into position, and the brakes won't open back up all the way on their own (with or without the speed fin installed).

In 30 years I've rarely had to take my bike to the shop for their help, but I may drop it off at the dealer, which will then take 2 weeks. See if they can get it working. But then when it gets gummed up again, will likely face same frustrations?

Thinking I should have either gone disc brake, or a bike like QR that can use regular/tririg calipers. So frustrated.

I spray a small amount of PL-100 on the wedges after cleaning the brakes, seems to do the trick for me. Be carefull not to spray this stuff on the brake pads though...

One thing I've noticed on both the front and rear brake, the 'rollers' at the tops of the brake arms, mine don't move, don't spin. Are they supposed to??? On the rear brake, I though maybe they had seized up due to sweat, but I tried washing/soaking them in penetrating lube as well as WD-40, still don't move.
Front brake didn't have any sweat on them, so not sure why they wouldn't rotate.

Good question, I will have to check next time I clean the brakes!

Run from that shop. If they think putting in a new brake cable is hard, then they probably shouldn't be touching your bike.

Yes you are right. You need to remove the brake cable, tighten up the brake lever, then put in a new cable. Once you have the new cable fed through, put the wedge on before you cut the cable. I've had trouble getting the wedge on with an already cut cable. Overall, its not hard, just take your time and you'll learn how silly your LBS is being.

Following up, finally got around to doing this. And yes, you were right, it was not that hard. The hardest part was getting the old cable out from the brake lever. After that, the new cable went in, no problem. Maybe I got lucky.

The nut on the little wedge was frozen too, but came loose after being sprayed with some WD40.

Yours is a Gen2 SC, yes?
So thats odd, cause Mitch replied to an email I sent him, saying they are fixed and that the wedge just slides on them......
Frustration continues...

Silly question, but did you trim the cable super-close to the wedge? I had that problem as well when I left it a little too long. Good luck!

Nope.
I did just pick up the bike from the LBS today, and they do have it working well, but because of how they are operating (covd, etc) I didn't get to talk to the mechanic to ask specifically how he fixed it. The work order had a few notes on it, one saying that I had the 'wrong spacers fitted for wide wheels'......not sure if that meant wrong washers behind the pads? And then just said reset the set screws and set up from scratch. But I had gone through that too, so not sure what he did different. The front brake is very smooth, the rear brake feels more clunky/rough, but it does return to its starting position..

If I remember correctly, the service manual gives two positions for the Brake Pad Carriers washers, depending on the width of the wheel.

I've not read through this entire thread, but having just picked up a gen2 speed concept size xs which has 650c wheels, is there a draft box specific to the smaller frame with the smaller wheels?.. or is it a one size fits all?

Thanks.

No. I just ordered mine on Tuesday. Not sure what they could do to make it better. It’s still one of the fastest bikes out there.
