XTR V Brake Set Up

[julesg007]

Evening Forum,

I'd be very grateful for some help.

I've got the M951 version of the brake and not having run these before I'd appreciate any guidance in getting them set up properly.

For example, I can see there is a some form of adjustment but not sure what it for and how far from the rim should the block be.

Sorry for seeming to be a bit of a dim wit but have only used fairly basic canti's upto now.

Thanks a bunch

Jules

Adjust the spacers so the arms are almost parallel when the blocks touch the rims. To set the blocks attach the brake cable then take the spring tension off one side by slipping the spring arm behind the small post on the brake arm. This pushes the brake block hard against the rim. Tighten the block with a bit of toe in, use a bit of thin card (2mm is about right) squashed between the rear end of the block and rim. Tighten the allen bolt whilst holding everything in position. Do the other side. Bobs your uncle.

Hi,

Thanks for the reply - the information is as always first class.

There is, however, just one other question. From the attached photo you'll see some form of adjustment that can be made. Are you able to advise what it is for and how to set it correctly.

Thanks again and happy retro riding

Jules

Thats to adjust the tension so that both arms move the same when used. Fit and then adjust.

The screw is to centre the brakes on the rim. Adjust one to make the blocks the same distance from the rim on both sides.

Beat me to it

thats the spring tensioner.
If when set up, the brake arms have a tendency to lean to the left or to the right, you can apply tension to the appropriate side in order to balance them up and keep everything parrallel.

I tend to run quite a bit of tension on both sides (balanced to keep things straight of course) and as a result you end up with a nice sharp pulling feeling at the lever, and more instant power at the rim.
Just be careful to use a good quality screwdriver as the screw heads tend to be soft and thread easily.

when you pull the lever and the pads are in contact with the rim,there should be a positive feeling.It shouldnt feel spongy in any way

Unless it is a Ti frame. In that case it is called modulation.

Hi All,

A huge thank you to you all.

I also use another forum for more modern bikes and in comparison this is a much more friendly and helpful forum.

You are all a real credit to the forum - 1st class.

Keep it retro
