Brake hose clamp help please

[phil-b]

I bought a used trek fx 7.3

It was missing a break hose clamp but I don’t know what type I need to replace it. It is of a style I have not seen before. On the bike the is a round channel

Can anyone help me with this please

That's block welded to the frame is not a clamp, but a termination point.

It was invented by Satan.

I assume you're tring to fit the cable on the right (with the tape) into the block. I can't see through tape but it looks to me as if you have a continuous cable without a break in the housing. The block is designed for terminating the housing, then run an exposed length, then entering another block upstream where the housing continues again.

You have two choices. Cut the housing, fit a ferrule at each end (just like the other cables in there already) and fit it like that.

Alternatively, file out the channel so that the housing can slide through it and create one continuous cable. This lasts a long time as opposed to the exposed housing that quickly deteriorates and causes sluggish cable movements. The downside of the latter process is that you don't have a rat-tail file, will probably scratch the frame if you don't mask it off carefully and, that the cable may rattle against the frame. The latter is easy to fix. Imagination.

DO NOT attempt to drill out the channel. Your chuck will eat the frame.


On second throughts, you may be lucky and the brake section of that termination point is already cable housing-ready. See if there isn't a slot through the bottom of the block to take a cable tie.

That's not a termination point - it's much larger than the other two and is really just to guide the cable for the rear brake. Normally you'd have a hole in it to attach with a zip tie. If you want the cable to stay in the guide you may want to zip tie it to one of the gear cables before it goes through the guide. I think that's the best you can do.

Yes I want the right cable with the tape to fit in the empty slot.

The cable with the tape is a hydraulic tube so can’t be cut.

The slot on the block is straight through and has no edges to capture a ferrule. If it did there are adapters you can buy .

The slot is wider than the standard ferrule holders.

Yes this is correct it is just a wide slot

The slot is too wide to hold a cable and that’s why I thought there may be something missing.

I put tape on the cable to widen it hoping it would stay in place but it doesn’t

I’d try splitting a bit of rubber tubing to go over the pipe. Might give enough squeeze fixation to hold it?

Yes this might work . I can’t think of any other options

 

[fossyant]

You could get a couple of the cable holders - holds one cable to the other, or use a zip tie - I'd zip tie it a bit further up.

You'd expect a C Clip to work, but there doesn't seem to be a slot.

No slot and no holes for a zip tie and it is far to wide to hold a cable I’m still puzzled on how it is supposed to work

Magic ?

Yep it's a hydraulic brake pipe, I'd expect there to be a split rubber sleeve to sit over the pipe and hold it secure, has it fallen off

Here is a pic of a similar Trek 7.3 (pic 6) which clearly shows a rubber/plastic sleeve over the hydraulic pipe in two cable-guides.
