Hi Guys, My second post on here, so be kind I have followed Kiffsta's guide to bleeding the front brakes on a Suzuki Across (http://www.2fiftycc.com/index.php?topic=213.msg724#new). However i haven't had much success just want to share my scenario with all and hope someone can give me some tips. Originally, i had an issue where my front master brake cylinder was leaking. I suspected it was from the top. However not knowing for sure thought my best bet to disassemble and test. I took it off the handlebars removed the brake light switch and the brake line and proceeded to test, and it didn't seem the like cylinder itself was leaking only from the top under pressure. However i didn't reassemble the unit rather left it on the side until i got my new diaphragm, cylinder head/top and screws. During this period it got completely drained of brake fluid and the lines were taped up to prevent dirt getting in, but obviously not air tight. Ok, got the parts, reassembled. And put in some new dot4 brake fluid. As per Kiffstas tutorial i cycled through the first full reservoir of brake fluid to empty out any old liquid. I did this till the reservoir was dry again. At which point i started the actual bleeding steps 6 - 8, i have done this for a whole 3-4 full reservoirs. And I'm still not getting a steady stream of liquid on every bleed, and my brake steel feels as loose and spongy as when i started. One thing i was unsure about, was while doing the bleeding i didn't have the master cylinder bolted up. It was just open, but i didn't let the fluid run out at any stage. Really desperate for help guys, i got 0 brakes when i hit the lever. Please help. Thanks in advance, Rob
Hey Rob Sounds like air is getting in somewhere, when you re-attached the brake line to the master cylinder and the brake caliper using the banjo bolt, did you make sure the washers were in place, see attached pic, also you need to make sure the banjo bolts are tight, if you have a torque wrech, the setting is listed on the pic below. Cheers Chris
Hi Kiffsta, Luckily i never undid the bolt connecting to the caliper..only the one that was connected to master cylinder. I will attempt to rwtighten and re-attempt..just wanted to ask in peoples experience how long/how many pump and bleed cycles should it take ?
Hi Everyone, Just managed to get this sorted and wanted to share my experience. It seems that I had air bubbles stuck in the actual master cylinder. I saw a post where someone actually opened the banjo on the brake line and master cylinder and bleed the master cylinder from there. Worked a charm. Basically: Open Banjo Squeeze Lever Close Banjo Let go of Lever Did this about three/four times and instant brake pressure on the lever. Big shout out to Kiffsta, appreciate the schematic and your help mate. Rob
