crispyboy Posted September 9, 2009 Report Share Posted September 9, 2009 Well i got my booster out and put it on my bike yesterday and then set the pads up and started to tighten the bolts.I pulled the lever and the cylinder just popped out of the clamps.I dont want to go any tighter as i could mess the threads up.I them took the booster off the frame.Went riding and it was fine Any one ever had this problem ?solved it ?

Skoze Posted September 9, 2009 Report Share Posted September 9, 2009 Are the spacers you're using the right length? Quote Link to comment Share on other sites More sharing options...
Phatmike Posted September 9, 2009 Report Share Posted September 9, 2009 I'm assuming you're using longer bolts with the booster, Ryan?If so, how much longer are they than the current bolts - you need to check that distance, with the combined booster+spacers. If they're longer then they may be fouling on the frame somewhere meaning the clamps aren't being done up tight. Quote Link to comment Share on other sites More sharing options...
crispyboy Posted September 9, 2009 Author Report Share Posted September 9, 2009 Shut up you complete retard!!!!!!!!What clamps are you using my man?Magura onesAre the spacers you're using the right length?im using washers which are the same length as the standard spacersI'm assuming you're using longer bolts with the booster, Ryan?If so, how much longer are they than the current bolts - you need to check that distance, with the combined booster+spacers.

Fish-Finger-er Posted September 9, 2009 Report Share Posted September 9, 2009 assuming your using longer bolts, and washers, are you sure the threads arent bottoming out, before you actually start pushing down on the clamps?? Quote Link to comment Share on other sites More sharing options...

LukasMcNeal Posted September 9, 2009 Report Share Posted September 9, 2009 Bottoming out is where the bolts are hitting the frame after the 4 bolt mount. Quote Link to comment Share on other sites More sharing options...

Simpson Posted September 9, 2009 Report Share Posted September 9, 2009 Do you mean only abit of thread going into the frame ?No he means the whole thread going in to the bottom, so that it feels like there done up tight, but because the bolts are too long there not clamping propperly.

N.Wood Posted September 9, 2009 Report Share Posted September 9, 2009 No. If you have a threaded hole with a plate on the bottom (so the bolt can't go all the way through) then using a long bolt will mean the head of the bolt is in a higher position than a shorter bolt when the bolt is wound in fully so it can't go any further (the bottom of the bolt is touching the bottom of the threaded hole). With me so far?If you use long bolt, the heads will be higher. This moght mean the clamps arn't getting enough force on them, because the bottom of the bolt hits the bottom of the threaded hole before the clamps are tight enough.Make sense?

Katkin Posted September 9, 2009 Report Share Posted September 9, 2009 (edited) Sounds like your helicoils are winding themselves in further.Or maybe the helicoils outer thread is FUBARMattP.S I'm dressed as a woman....again Edited September 9, 2009 by Katkin Quote Link to comment Share on other sites More sharing options...
Skoze Posted September 9, 2009 Report Share Posted September 9, 2009 When i tighten them up so the cylinders dont pop out of the clamps the bolt just spins when i get it tight enough ??Something in there is royally f**ked. Take the brake off and tighten it til it stops, gently put some pressure on and see what's spinning round (at a guess, the helicoils in the frame) You wont cause any more damage to it than you already have.

Matt Vandart Posted September 9, 2009 Report Share Posted September 9, 2009 Thats better wig off, dress binned..........As I was saying, sounds as though the thread the actual helicoil sits in may be buggered.Matt Quote Link to comment Share on other sites More sharing options...

It does technically weaken the frame little though... Edited September 9, 2009 by Nickkkkk Quote Link to comment Share on other sites More sharing options...
N.Wood Posted September 9, 2009 Report Share Posted September 9, 2009 Right i think that to I just put new helicoils in every mount on monday And i not that rubbish at using threads something to do with steel bolts ?Steel bolts wont be a problem if they're the same size and thread pitch as the ti ones. Try using the ti ones and see if it still happens? Quote Link to comment Share on other sites More sharing options...
