Canot get the rear brake to bleed - 2007 Yamaha XT 125 R

Bleed master cylinder ,with brake lines disconnected,then connect brake lines and bleed each brake line at master cylinder. then right rear brake,then left rear brake,then right front brake and last,left front brake.

Michael:

You must start bleeding the brakes at the wheel farthest from the master cylinder (usually the right rear), then the next farthest from the master cylinder, then the next, then the closest. If your master cylinder is at the left front of the car, start with the right rear, then the left rear, then the right front, then the left front. If you don't bleed the brakes in the correct order, you are just shifting the air in the lines from one line to another. Make sure that you close the bleeder before letting the brake pedal up, and the engine should not be running when you bleed the brakes... Make sure that the emergency brake is off. Make sure that the master cylinder does not run out of brake fluid at any time that you are bleeding the brakes.

1. If there is a substantial fluid eruption, there are air bubbles still trapped in the system. You must repeat the bleeding procedure to remove that air. A modest disturbance in the fluid returning to the reservoir indicates a properly bled brakesystem.

How to Bleed Brakes - Tips on Bleeding Brakes

Some clutches can be fearsomely difficult to bleed successfully. In cases of difficulty it is worth trying reverse bleeding...

Connect the clutch bleeder and the nearest brake bleeder together with some well-fitting tubing, open both bleed screws and have an assistant pump the brake pedal. Make certain the brake reservoir is kept topped up and remove excess fluid from the clutch reservoir before it overflows.

Half a dozen pumps usually is sufficient, hold the pedal down and close both bleed screws.

Loosen the bleed ******* off 1 at a time , if no fluid comes out the nipple is blocked clean them or change them .

i dont know what this car is but it sounds like you need to adjust the rear brakes and also there may be air still in the sytem, there are many cars that cross brake systems so if you are working on the left rear wheel you would also need to bleed the right front wheel, heres what i would do make sure to fill the brake fluid and always keep an eye on the level as you are bleeding the brakes, start at the right rear wheel and bleed it a few times then move to the left rear wheel, bleed that then go to the right front and bleed that one and last is the left front and that should solve ant air in the system problem, also make sure there are no leaks in any of the brake lines. good day.

Your rear brake pedal operates the rear caliper and the front disc. When you tried to bleed the left front caliper you let air into the rear brake system. Bleed the rear brake and front left caliper using the rear brake pedal that should restore the rear (and front) brakes.

Did you bleed rear brakes also? Should do all 4 whenever bleeding brakes starting w/ right rear, left rear, right front then left front. Sounds like air in lines.

To change the switch, first unplug the wires at the switch. Screw the old switch out and install the new switch into the tee connector. Do not depress either brake lever while the switch is out. Tighten the switch and reconnect the wires.

Usually you don't have to bleed any air out of the brake system but check the rear brakes for proper operaion. If the rear brake pedal goes too far down, bleed the brakes at the rear caliper. Make sure you don't run the rear brake master cylinder dry while bleeding the rear brake. Use only the approved type of brake fluid, do not mix the different types of fluid. Make sure the rear brakes are working properly before riding the bike.

Its probably how your bleeding your brakes, but first make sure the bleeding nipples are facing upward. You should bleed diagonaly, front pass wheel then rear driver wheel. Then front driver wheel and rear pass wheel. The abs light has its own computer your have to get it scanned to clear the codes and turn off the light
