Shuddering in brake lever
 

I finally fit my new TKC80 on the front earlier this week. I had to take it to a shop to get it done and after leaving there I experience a shudder in my brake leaver when I do moderate to hard braking.

Is this the new tire or did they damage one of my discs? I figured if it was one of my discs I would feel while I'm riding as well but I don't.

Any ideas?

if you can get the wheel in the air & give it a spin you will be able to hear if the brake is rubbing. It might also be worth checking your tyre pressure. But I'd say it's more then likely just the big blocks on the tyre causing it.

If you're not used to something as knobbly as a TKC80, then they will feel and appear to do strange things at first. They tend to judder through the brakes, fall into bends and vibrate through the seat bars and pegs at low speeds basically as you roll on and off the tread blocks. A high speed weave at 70+ isn't unheard of either, but depends a great deal on suspension and bike setup. This is one of the reasons I have stopped using them.

They do get significantly better with respect to all the above (except the low speed vibration) as they bed in, maybe after 200-300 miles or so. Also, during that time, you will become accustomed to them as well.

One point of note is that TKCs on the Tenere generally behave better at slightly lower pressures than the handbook states which are geared more road orientated tyres. Everyone's different, but over the years and after many sets I found 28/31 psi (on the road) to be best for an optimum balance of grip, comfort and tyre wear. Also, are you sure the front has been mounted the right way round? They might not look directional, but the they are.

Hi worst case scenario is a bent disc, but it would be a good idea to loosen the bottom clamps next to the axle, give the suspension a good bounce and retighten the bolts Don't over tighten just nip them up. The forks could be slightly misaligned.

Riding on the new front had me worried for the first couple of days. Felt like it had a mind of its own. It does take some getting use to. I will reduce the pressure, check the direction and see if anything improves.

Nothing serious. I just don't want to use the bike if there is something wrong with it that needs fixing.
