Phill Posted March 9, 2018 Share Posted March 9, 2018 I have a Yamaha ybr125 and I've done 700 miles with it and I've noticed that the brake fluid is at the lower mark when the bike is on the centre stand and the handlebar is straight. Should I top it up? If yes, when should I stop?And regarding the oil lever, I've noticed that when I got the bike the oil on the dipstick was nearly to the max level, now it sits at halfway between max and min. level. When should I worry? The oil is a dark brown colour, not black.Thanks!Sent from my SM-G950F using Tapatalk Quote Link to comment Share on other sites More sharing options...
Stu Posted March 9, 2018 Share Posted March 9, 2018 First of all check your brake pads before topping up the brake fluid As they wear then fluid goes down and when you put new pads in and push the pistons back in the caliper the fluid will rise If the pads are good then top it up to just below max which should leave you enough room to compensate for the wear already taken place on the pads As for the oil level you need to worry when its below min but you need to be topping it up before its gets to min ideally Halfway between max and min is fine Quote Link to comment Share on other sites More sharing options...
Westbeef Posted March 9, 2018 Share Posted March 9, 2018 What's the brake fluid level like when you're sat on the bike and it's upright? Quote Link to comment Share on other sites More sharing options...

Probably the same as when its on the centre stand and straight like it is now I thought that, but doesn't the Centre stand tilt the front forward? That's why I asked Quote Link to comment Share on other sites More sharing options...

Phill Posted March 9, 2018 Author Share Posted March 9, 2018 The level is higher but just a tad!Sent from my SM-G950F using Tapatalk Quote Link to comment Share on other sites More sharing options...
megawatt Posted March 9, 2018 Share Posted March 9, 2018 That looks OK depending on how worn the pads are. The reservoir should be as level as possible. If the pads are due to be changed, I wouldn't top up the oil level. Quote Link to comment Share on other sites More sharing options...
Phill Posted March 9, 2018 Author Share Posted March 9, 2018 The pare were changed at the last mot so they're basicly new.Sent from my SM-G950F using Tapatalk Quote Link to comment Share on other sites More sharing options...

Could do with a little top up . The main idea is to keep the bottom of the container covered with at least three quarters of an inch of brake fluid .

Phill Posted March 9, 2018 Author Share Posted March 9, 2018 I got some DOT4 today(as per manual, DOT 3 is fine aswell), i will top it up tomorrow or sunday, today is raining and i dont want to get the moisture in the brake system .I will top it up until the window is 'full' of brake fluid, i just need to get a syringe to do it accurate Quote Link to comment Share on other sites More sharing options...

Don't forget to leave room for the rubber diaphragm and take the precaution of covering the tank with a cloth in case of spillage . When you open the new bottle of brake fluid make two small holes in the foil cap for easy pouring .

Phill Posted March 9, 2018 Author Share Posted March 9, 2018 I don't think it's a Chinese knock off... they don't usually have FI, like the honley hd2 which( based on the newer ybr with the redesigned headlight) it was on carburettor.Sent from my SM-G950F using Tapatalk Quote Link to comment Share on other sites More sharing options...

Phill Posted March 10, 2018 Author Share Posted March 10, 2018 Yeah that's true .Topped up my brake fluid. There wasn't much to top up anyways, like 10 mls. The reservoir was actually very full despite of the 'low" reading on the window.Sent from my SM-G950F using Tapatalk Quote Link to comment Share on other sites More sharing options...
