!Harris! Posted April 28, 2008 Report Share Posted April 28, 2008 I think the answer to all this gumbo is to get a new back brake Xan ! Quote Link to comment Share on other sites More sharing options...
Alex Dark Posted April 28, 2008 Report Share Posted April 28, 2008 (edited) is it 05 or 04 style? either way ill try and help...For an 04 you need to undo the 5mm allen key bolt that holds the blade on....take the bolt out and pull the blade off with the tpa and piston pokey bit ( you'll know what i mean when you see it )....now disconnect the main hydraulic line with an 8mm spanner....then geta small allen key, poke it through the bleed hole or the line connection hole.....now put some pressurte on it and the piston should just pop out...once out, you have to clean the inside of the lever bodya dn the piston....use some kitchen roll and wd40 for both...take the o-ring off the pistona nd check to make sure it's not damaged....if not then lube it up with a smear of vaseline and put it back together.....if its knacked...go donw to your local hardware shop and take th o-ring with and you buy one.For an 05 you need to undo the 5mm allen key bolt that holds the blade on....take the bolt out and pull the blade off with the tpa and piston pokey bit ( you'll know what i mean when you see it )....now take the bleed screw out with a 5mm allen key....you now need to have either some very strong hand or nole grips / vice / adjustable spanner etc. Put a pair of pads in the magura then use your chosen tool to clamp the pad to the slave piston so it cannot move. You now need to get a bleed kit and connect it to the bleed bolt.....fill the syringe with water, then force it into the lever body...the slave pads wont move, so effectively sealing the system, and the piston will pop out.....once out, you have to clean the inside of the lever bodya dn the piston....use some kitchen roll and wd40 for both...take the o-ring off the pistona nd check to make sure it's not damaged....if not then lube it up with a smear of vaseline and put it back together.....if its knacked...go donw to your local hardware shop and take th o-ring with and you buy one.When you think you've checked the o-ring and lubed / cleaned everything, whack it all back together. I personally like to pressure-test my brakes once this is done. basically.....have the brake fully assembled, and stick some kind of clamping device that will hold the pads into the slave, stopping their movement out wards...now, while attempting to watch all the connections, pull hard on the lever....im not talking like a complete retard with every ounce of power....just gradually apply the pressure until you think its enough ( or your hand hurts )...at this stage something usually leaks....now retighten the barb / olive if its at fault, replace the lever o-ring, replace the knackered hosing , replace the faulty slave cylinder, bodge the tpa etc ( delete as applicable ).No repsonsibility is taken for you pulling the brake like a native and breaking it so be careful......I think that post is worthy of validation...if i wasn't already validated WIKI?
