I put on a new rear caliper today.I can't seem to get pressure built up.How long does it take?Do I fill the caliper some how first or what.Please help. Can someone walk me through this. | ||

Standard bleeding is thus--fill reservoir,work brake pedal repeatedly then hold down while cracking open bleed screw on caliper.You can run a hose from bleeder to jar with brake fluid to see the bubbles come out--ro not.But you will make a mess.Repeat as necessary.Do not let go of brake pedal while bleeder is open or all that air will go tight back in.Do not let reservoir get too low or--same as above---be warned,motorcycle calipers are a bitch to bleed.If you have a way to squirt fluid--like a large syringe--force fluid back through system by injecting fuid at bleeder screw.This works really well. | ||

Further to what Fireman Jim says, make sure you pull the brake pedal fully up before stroking it down again. Not doing this prevents the caliper bleeding properly. Mine bleeds fully in about 5 or 6 strokes if I pull the pedal up fully before stroking downwards. HTH. Regards Steve www.ukbeg.com steve_s@ukbeg.com | ||

Just to let you know this caliper is empty.So how long will it take to bleed.Seemed I spent 1 hour trying to pump pressure.Still could not seem to build up pressure. | ||

Get yourself a "mightyvac" Then just suck the fluid into the caliper. Makes it a very easy job. Trying to bleed the rear brakes by pumping the lever is almost impossible due to the low volume. | ||

Here is what I like to do. Just dug out this link for syringes. I think the Catheter tips will work well, but have yet to see them. I imagine you'd be able to heat up a piece of clear tubing (that will fit your bleeder nipple) and expand it to fit the catheter tip. Secure with silicone/zip tie. Henrik | ||

In the shade of my personal mechanic-ing tree, I have been known to apply suction orally to a long piece of tubing attached to the bleeder nipple. Long is important so you can see the fluid before it gets in your mouth! Disclaimers: Don't try this at home, I'm a trained professional on a closed course, blah, blah, blah... rt ...just in case you're wondering, brake fluid tastes like s***... | ||

Thing! Don't I know it! Not nearly as bad tasting as gasoline though, I remember one time... Oh wait. Never mind. Geesh. Who would be so dumb as to suck brake fluid or gas?  | ||

Back when I was perpetually broke I kinda got used to the taste of gas. I used to keep a length of skinny fuel line wrapped around the frame on my ol' Triumph--my dad referred to it as my "Arkansas credit card"... Then I learned the secret to siphoning gas: You put the hose in the donor vehicle's tank, then wrap a rag (or hanky, or t-shirt, whatever you've got) around the hose and stuff it down into the filler neck so it sorta seals the annulus. Blow vigorously into the hose so as to pressurize the donor tank and Voila! gas flows out like magic! rt as a side note, this is best done when the donor vehicle's owner isn't around, unless he's a friend of yours... | ||

nothing quite like chasing the kid around belching gasoline fumes at her! i kept getting a longer hose and then a clear one and still can't get it right. |
