How to replace/bleed disk fluid in Royal Enfield

Warning :
1.Disk brake fluid is very corrosive and can damage paint so cover the bike parts with some cloth.
2. You should be very careful in following the instructions and have patience otherwise you may end up air in the disk brake system and zero braking.

What we need:

100 ml of DOT3 or DOT4 brake fluid. I could find DOT3. Only use from sealed bottle.
8 mm Ring spanner [Warning : Open end wrench/spanner will not work here and may damage the nut!!]
Philips screw driver
Transparent pipe around 12 inch in length.
Empty plastic bottle

Step 1: Open the Main Fluid reservoir using Philips screw driver and you will see white plastic cover.

Warning : Be very careful while removing screw with screw driver. first fix the screwdriver properly into screw head use some force downwards as well and then remove it . The head of screw is made of very soft metal and it can get damaged even if screwdriver slip even once !!!! If screw head is damaged , you will not be able to remove it.

Step 2 : Remove White cover , you will see rubber diaphragm .

Step 3: Remove Rubber diaphragm and you will be able to see old disk fluid.

Step4: Here is the bleeder nut on the disk brake assembly .

Step 5 : Remove the cap from bleeder nut and fix 8 mm spanner to it . Attach it at such an angle so that you can move it freely up and down.
Warning:Don’t open this nut yet.

Step 5:Attach transparent pipe to it and put another end of pipe in to the empty plastic bottle.

Step 6: The reservoir should be filled so that air should not be able to enter in disk pipe.
Loose the bleeder nut by pressing the 8 mm spanner downwards.You will see the fluid coming out of the pipe.

Step 7: Be very careful in following step : Press the front brake lever to increase the pressure in system Keep holding the brake lever completely and tighten the bleeder screw again to prevent air entering in the circuit AND then release the brake lever.
Whenever disk brake lever is pressed you will see old fluid going to the bottle. Make sure you don’t release the brake lever with bleeder nut open otherwise it will suck the air through bleeder nut.Also always keep enough fluid in master cylinder.

Step 8: Top up the Fluid reservoir with fresh fluid from bottle.

Repeat the step 6 , 7 and 8 multiple times. i.e. [Loosen bleeder nut —> press the brake lever—>close the bleeder nut—> top up the main cylinder —>release the brake lever ]
Things to keep in mind :
Never Release the front disk brake lever when bleeder nut is loose.
Never let the Master Fluid reservoir be empty otherwise system may suck air through it.
Eventually you will see fresh fluid ,good in color coming out of pipe and getting stored in to bottle.

Finally all the fluid is clean and fresh in Fluid reservoir .
