Well after a normal bleed, reverse bleed, and nipple bleed abs my back brake is...... EXACTLY THE SAME! Aghhhhhhhh!! I give up I've never had so much trouble with a brake especially as the bikes nearly new. I've had the bike a week today and not ridden it yet as I need brake doing so I can take bike for its first Mot. Going to have to take it somewhere :-(
If you pump it it will a bit but then if you leave it 5 secs it's gone again, it's killing me as I need to get it through the mot. All I can think is to find someone near me (derby) who can help me and get it moted at the same time. As I can't really ride it to place to place while no mot
It still has air in it (somewhere) or the pads are lifting too far back off the disks (new rubber dust seals required?). Pads contaminated, disks oily?
Assuming your saying you have very long pedal travel, Fit the bleed nipple to the abs pump as descibed by ACT and a link in an earlier post. The abs pump is the highest point of the system, and unless you do a real good job with a pressure bleeder you wont get all the air out. Same goes with the rear caliper. You must remove thwe wheel, and lift the caliper up as high as you can (i.e. seat height) with the nipple upper most. Otherwise a bubble of air will still remain in the caliper. If youve only recently bought the bike I would be speaking to the supplying dealer about it too.
Well after booking my bike in next week to have my brake sorted, it was playing on my mind. I don't like being defeated so I thought I'll give it one last ditch attempt to bleed this rear. This time I took the caliper off and hung it above the bike, cables really quite long!. I pumped nearly 300ml of new fluid it and on every stroke bubbles appeared, just shows that they hide.. On the sight of no more I locked if the caliper nipple. Put the bike back together wheel back on etc and prayed!! Pressed the pedal couple of times and what do you know a rear brake appeared!! Not the best in the world but it works non the less. So today it's mot time so finally I can ride my new toy, and hopefully get out touring in September. Many thanks to everyone who has advised me over this.
Hi all. Bought a new MTS 1200 ABS a month ago already done 1200 miles. I love it. So smooth and planted at speed a bit lumpy low down but had a tiger 800 before so a bit spoilt with the silky triple engine. Problem is, I have the non existent back brake syndrome. Took it in for its 600 mile service, they plastered the chain with lube and ever since the brake has been crap. The back wheel seems to create a vortex that pulls air through. The caliper and wheel were covered in a splattering of grease. I cleaned the disc with brake cleaner but not the pads as I was taking it in for the panniers to be fitted, so asked the dealer to have a look. Result? No, still the same. I presume dealers know about "back brake syndrome". Do they know about Air Cons fix bleeding the brake high up etc? Or do they tell you that they have looked at it, send you away and hope you fix it yourself. Which seems to be, in my case. Being short of leg, I feel a back brake is essential when wobbling about at low speed (although its sooo well balanced). At the moment at a standstill I can put the brake on with my foot and move the bike with my other, even with short legs for purchase. There is resistance at the pedal so I presume its not air but lube contamination on the pads? Im going to get back to dealer again and pester, or is it quicker and less hassle to buy new pads and put them on myself? At least you know its done properly. I should not be thinking like this, I have a warranty god dam it. If the back brake does not work properly its not fit for purpose. Right? My call is. Do owners take care when lubing there chains ie does the problem seem to reoccur coincident with chain lubing ? and do owners have a more of a problem when scottoilers etc are fitted?
