Front brake tension screw untensioning itself every ride.(7 posts)

Front brake tension screw untensioning itself every ride.Eug

My front brake tension screw loosens itself up every time I hit the brake. In fact I can watch it do it just by getting off the bike and pressing the brake lever a number of times.

To ask a stoopid question, is there something I can put on it to stop it from doing this? It already has this blue plastic collar on the threads, presumably to prevent this very problem.

Does this just mean I've just stripped that plastic on the threads? I'll get some new screws when I get the chance but I just hope I won't have the same problem.

The levers are 105, but the brake itself doesn't say what it is.
Loctite or beeswax...Silverback

Assuming it's not stripped, you could try putting either Loctite (auto parts place) or beeswax on the threads. I use beeswax on nearly every threaded fastener since I had Rivendell toss a lump of it in with an order.
Tried paraffin wax - no worky. Loctite - isn't it bad for bikes?Eug

Tried using paraffin was (semi-melted). Doesn't work.

I'm a little apprehensive about Loctite since I've never used it before and I don't want the screw to seize.
not as bad as having screws unscrewing themselves - nmrussw19

It won't completely seize with Loctite?Eug

I'd hate to have an unadjustable brake.

It shouldn't seize with the blue loctite. It might if you use the more permanent red type of loctite. Most replacable brake shoes are assembled with blue loctite. Many pedal manufacturers recommend using blue loctite on cleat bolts.
Thx. Bought the blue. Works OK for now.Eug
