JoeM Posted March 1, 2008 Report Share Posted March 1, 2008 So recently I've been running a water bleed due to me not having a syringe, but, I've found myself having to rebleed it every couple of weeks due to the brake pulling to far in. Its not my pads, there set up perfect. Could it be down to the fact my TPA is fecked? Or is it just I'm bleeding wrongly?To water bleed I:Unscrew the bleed screws on both pistons under water.Hold the hole on the leaver hole(master cyclinder?).Pump the brake then realease the my thumb from the leaver hole and let go of leaver.Continue.Then after about 1 week of riding it starts to become wank. Help? Quote Link to comment Share on other sites More sharing options...
RossMcd Posted March 1, 2008 Report Share Posted March 1, 2008 Well my brake bolt is rounded so i take all of the cables off and rebuild the brake under water. I make sure there is no air in the cables by sucking the water through lol. works every time Quote Link to comment Share on other sites More sharing options...
BenLeacock™ Posted March 1, 2008 Report Share Posted March 1, 2008 I undo them both under water, pump it for bout 2mins slowly, tighten them back up under water, and they always seem to work ? Ur not using dengura are you ? If so you might have a leak ? Quote Link to comment Share on other sites More sharing options...

Andeee Posted March 1, 2008 Report Share Posted March 1, 2008 I have one thing to say: Do not bleed hydraulic brakes with the incorrect fluid. You will regret it. Quote Link to comment Share on other sites More sharing options...
mintsauce96 Posted March 1, 2008 Report Share Posted March 1, 2008 I have one thing to say: Do not bleed hydraulic brakes with the incorrect fluid. You will regret it.water bleeds rule Been running mine now in front and rear maggies for 3 years or so with no problems at all.Cheap Free , not as messy and seriously better braking imo (much more responsive) As for your problem, I've never bled without a syringe and never have any problems so can i suggest you get one? Will make bleeding so much easier!Something which may enable air to get into your system is how quickly you fill your bath / sink, if you stick the tap on full loads of tiny air bubbles will be floating around and therefore end up in your brakes, when they are sat in your system for a while they will start to form a large bubble causing your squishyness.Try running the tap real slow and down the edge of the bath / sink so the water does not get air trapped in?just guessing here so hope it helps!Kev Quote Link to comment Share on other sites More sharing options...

Revolver Posted March 1, 2008 Report Share Posted March 1, 2008 (edited) is there a guide for this, just tryed undoing the brake lever in my sink with water and nothing changed? ive seen the guide on wiki but its confusing for me. undo both the bleed bolts underwaterput your finger over the brake cylinder hole, and press the lever in -put your finger on the lever hole and take it off the brake hole, and release the lever.then repeatthus, you suck just water through the brake end and push water &/or air out of the lever end Edited March 1, 2008 by Disasterboy Quote Link to comment Share on other sites More sharing options...

JoeM Posted March 2, 2008 Author Report Share Posted March 2, 2008 "both the bleed bolts underwater" is there two? theres only one cable leading to the lever or am i also ment to do the actual brake?Theres one next to the hose going into the lever in a little hole, the other is on the piston.

Danny Posted March 2, 2008 Report Share Posted March 2, 2008 Sounds to me like you have a leak. Check your slave cylinders i know one of mine sprang a leak. The trouble with a water bleed is that you will struggle to notice it. Quote Link to comment Share on other sites More sharing options...
JoeM Posted March 2, 2008 Author Report Share Posted March 2, 2008 oh, so i cover the hole, remove the cable and pump the brake till all the air comes out?No, you place the brake into a bath/bucket, you undo both of the bolts (lever and piston), then you cover the hole on the piston and pull brake in, then remove your thumb/finger from the hole and let go of the lever and so on. If your brake has been bled with oil, keep going till ALL of the oil and air is out. Look in the wiki section.Ok, brakes just been bled, seems fine. I'll report back when it starts to go shite again. I think danny is right, I do have a slow leak. How can I check? I've looked other the break thuroughly(sp?) and can't see anything. Where is the most likely place for the leak to be?
