how to repair disc brake Pulsar 

Here is a step-by-step description of how to repair a Pulsar disc brake oil tank:
1. Gather your tools and materials.
You will need the following:
2. Locate the brake fluid reservoir.
The brake fluid reservoir is usually located on the handlebars, near the master cylinder. It is a clear, plastic container with a black cap.
3. Remove the old brake fluid reservoir.
Use a wrench to loosen the bolts that secure the reservoir to the handlebars. Then, carefully remove the reservoir from the bike.
4. Install the new brake fluid reservoir.
Place the new reservoir on the handlebars and secure it with the bolts. Then, tighten the bolts with a wrench.
5. Add brake fluid to the reservoir.
Use a funnel to add brake fluid to the reservoir. Be sure to add the correct type of brake fluid for your bike.
6. Replace the cap on the reservoir.
Tighten the cap with a wrench.
7. Bleed the brakes.
This will remove any air bubbles from the brake lines. To bleed the brakes, you will need a bleed kit. Follow the instructions in the bleed kit to bleed the brakes.
8. Test the brakes.
Once you have bled the brakes, test them to make sure they are working properly. Pull the brake lever and see if the brakes apply properly. If the brakes do not apply properly, you may need to adjust the brake pads.
