Doofa57 Posted July 24, 2019 Posted July 24, 2019 I applied my rear brake a bit hard and it bottomed out. No stopping power apart from the front so i hod a look and found this. The chain guide is not in place it i held in by a bolt at the back a a rubber bung thing at the front. so now i need to take the hose off get a new one. I am not looking forward to is beading the brakes. the brakes are the Combi Brake System so i haven't done this system before. Quote
Guest Richzx6r Posted July 24, 2019 Posted July 24, 2019 Oops....but who in their right mind would route the brake line there, unless they have engineered it to fail Quote
Doofa57 Posted July 25, 2019 Author Posted July 25, 2019 So I have replaced the hose with a new one. My new problem is the bike is fitted with combination brake system and ther is 3 nipples for the rear brake. 1 on the rear caliper 1 on a junction type box then 1 on the front brake. I haven't even attempt to bleed them yet I am sure ther must be a order to do them. time for some research Quote
Mississippi Bullfrog Posted July 25, 2019 Posted July 25, 2019 I've only ever bled non ABS systems. If it has ABS don't you need diagnostic kit to open the valves in the ABS unit? Quote
fastbob Posted July 25, 2019 Posted July 25, 2019 (edited) I've only ever bled non ABS systems. If it has ABS don't you need diagnostic kit to open the valves in the ABS unit? I wouldn't have thought it's going to be ABS on a Keeway but it is probably a linked system. I've seen a linked braking system on a Lexmoto that I helped someone with and it wasn't pretty . I'm sure the front came on when you operated the rear ( !? ) I wouldn't know where to start bleeding such a system to be honest .https://www.speedwaymotorcycles.co.uk/motorcycles/street/keewayrksgry/ Edited July 25, 2019 by fastbob Quote

But it seems a rather silly arrangement and unnecessarily complex for that kind of bike. Quote

But it seems a rather silly arrangement and unnecessarily complex for that kind of bike. That's what I thought when I worked on the Lexmoto Falcon but there it is . I've checked the specs by the way and this bike also has it . Thinking about it , it's lucky the entire system didn't fail . There must be a fail safe built in . On the subject of the Lexmoto , I didn't want to hurt the guy's feelings but what a joke . Essentially a rip off CBR 125 but with the same old air cooled CG based engine bunged in with some crude steel strap brackets hanging from the fake ally beam frame . Horrible ! Quote

Doofa57 Posted July 28, 2019 Author Posted July 28, 2019 the front calipers have 3 pistons 2 are operated from the front brake lever. the rear foot peddle operates the other front piston and the rear brake as normal. i think all eruro4 bikes have to have ABS or CBS. Quote

Only need special equipment if you get air in abs system. Quote

Pbassred Posted August 2, 2019 Posted August 2, 2019 I just checked the wife's Keyway Light. The pipes are on the other side. Thanks for the heads up though. Quote
