    Just fitting brake hose into the bracket on my Reba’s and the bolt has snapped in its hole, No great pressure was applied,

    Normally i’d screw directly into the bolt but the things tiny!

    Any Help/suggestions? I would be very grateful

    Bugger….
    Dont even think youll get an extractor in there – Local engineering company may be able to help ??

    Suggestion on other forums to center punch, drill and either reversing back up might be enough, if not a tapping a torx in to unscrew it. sounds possible,

    Might just get wrap electrical tape round it the bracket!

    My solution was to put the plastic bracket on the hose, zip tie it in place and forget about it. It is such a tiny screw. Trying to get it out would be more trouble than it was worth. Not very constructive, but as least you know you are not alone.

    I’ve just screwed into mine, with a bigger screw. Plenty of material around it to bite into. Works fine.

    I’ve been unlucky enough to come across two of these, the srcond time I was fortunate to have a stub to grip with a pair of specialist pin removal pliers used in my last job, the first had sheared off flush like yours, and had to be drilled (very difficult to centre, i’d recommend a snug fitting sleeve in the recess if possible), and re-tapped. Bike mechanics beware – do not let work experience boys near them, telling them not to touch them apparently isn’t enough, and may be followed by the sound of a snapping bolt, “Oh, it’s broken, sorry.”, and lots of cursing.

    You were fitting it at the time? Or trying to remove it?

    Cable ties fix everything.

    No. Duct Tape fixes everything.

    Screwing it in,

    Electrical tape makes the world go round although a zip tie is gonna look better.

    Thank you kindly for the tips!

    You want a screw extractor to remove the bolt. The video below shows you how. Personally I would use a hand drill rather than a power drill. I would also use a tap handle rather than an adjustable spanner. Screw Extractors tend to snap if the force isn’t applied directly downwards.

    Personally I regard this as skilled job. If you snap the screw extractor in the bolt you will never get it out. It only takes about 10 mins. But it must be done very carefully. A good motor garage should be able to do it.

    Screwing it in,

    OK then… Thing is, usually when you snap a bolt off trying to remove it, it means it’s well and truly stuck so when you get to extracting it, you’re dealing with the breakage but also the initial seizing. Whereas in your case it shouldn’t be that tightly held (I’m going to rashly assume it’s not overtightened, bottomed out, or crossthreaded 😉 )

    Screw extractors are basically evil, especially in the smaller sizes where snapping off the tip and converting your broken bolt into a broken bolt with an incredibly hard screw extractor stuck into it is probably just as likely an outcome as success, unless you’re pretty good. Even in skilled hands it can go wrong. It’s also depressingly easy to screw up the drilling since helpfully the bolt is hard and the fork is soft. So all in all, best to go to someone who’s properly good at it, if you can.

    If you want to do it yourself- centrepunch bolt. Soak it as well as you can with penetrating oil or diesel. Drill with left handed drill bit (no, that’s not a joke). Drilling might remove it by itself, and will also chuck a bit of heat into the bolt to help release it. Then screw extractor, biggest size you can use, and very very carefully.

    Not being funny, but personally I’d just cable tie it- after all that’s how all my forks do it.

    I would agree with all of what Northwind just said! Hence me saying it’s a skilled job. It is very satisfying getting the bolt out yourself…..

    Never tried Diesel as a penetrating lube. Does it work as well as Plus Gas?

    Ah, we crossposted, wouldn’t have bothered with all that if I’d seen yours 😳

    Diesel works very nearly as well as plusgas I reckon (though it’s hard to compare fairly) but it’s not as convenient to use. I suspect there’s not actually that much difference chemically, tbh. But I place more faith in plusgas because it comes in a can and costs more :mrgreen:

    Zip tie and a washer. One end through the washer round the brake hose and back through the washer round the fork. Works a treat and gets a better position for the hose normally
