Help I broke a bolt off in my front brake.

Wow, I feel really stupid. I was putting my front tire back on after I put on some new treads and while I was tighting the front brake to 40 Nm the bolt snapped off inside. What am I to do now? What are some ways I can get it out. I would really love to hear your advice.

Have you ever used these and do you have any tips. I was looking forward to a good long ride tomorrow and that is blown. Well a great learning opportunity. I will see if I can not get it out tomorrow. Thanks for the advice

Yes, more times than I care to admit.

 

Be sure that when you drill into the old bolt that you are fairly centered. I’d also buy the little “T” handle to use with the extractor. The whole setup will be 10-15 dollars to get the bolt out.

Take the good bolt to Lowes or Home Depot and get another one. You could still make your ride. The process should not take you but just a few minutes.

 

Glad to see you doing your own work. Your last mechanic was kinda flaky. I hear he was always out riding tongue.gif

Is the GS arrangement different to the RT? If so, disregard the rest of this. blush.gif

 

The RT caliper bolts are torqued to 30 Nm, not 40. If the bolt does break, the threaded portion should be quite easy to remove without recourse to 'specialised tools' (i.e., not in a general toolbox) -- both ends are accessible and should turn easily, if the threads were cleaned before assembly.

 

The bolts are not general-purpose types and should be replaced with high-tensile strength type as a minimum, but preferably with a new OE bolt.

Just replaced my rusty ones for stainless steel bolts

big difference in looks but possibly a small loss of temper

rating (within calculated sheer force acceptable tolerance rating)

Stainless bolt into aluminum fork leg is a really nice galvanic couple. Watch out for corrosion.

 

I did this several years ago, haven't had any problems so far. Been through numerous tire changes since then, so the bolts get inspected regularly, and I haven't noticed any signs of corrosion. OTOH, I would expect major issues if this combination were ridden in salty conditions, i.e. winter or a lot of time at the sea shore.

40 Newton meters. Strange measurement. Is that how far the apple falls befor hitting ol'Newty on the head? Could be fatal, like 1/4 turn past snap off.

A deft touch on a bolt with your hands has worked for me for years, 'cept when I forgot to snug up the caliper bolts and lost one...opps dopeslap.gif

Even your mechanical administrations require you calibrate the torque wrench occassionally and never leave it set except to '0'.

When in doubt let the dealer screw it up for you. dopeslap.gif

I agree I need to pay more attention. I lost a rear brake mounting bolt while on a trip so I want to make sure they are tight and at the right amount of tension. So I have learned my lesson that I need to pay attention more closely to the fine details.

Thanks for all the great advice.

Yea it is fixed I have removed the bolt and I am waiting to get another one from A&S. I can not find one around here. Home Depot and the do it yourself centers do not carry the bolts.

I got a nice metric bolt at OSH when I lost the one on my R65LS. Wasn't exactly like an OEM but it got the bike on the road. OSH had, last time I looked, an interesting supply of metric in regular and stainless. wave.gif
