Brakes problem

I changed my ubj . I had to loosen the brake line, and all of fluid came out. Resievor was empty. I refilled it but now brakes dont work with brake sign on. Does anyone know how i can fix this? thank you.

Do i need to bleed the master cylinder?
Or just the brakes?

 

Yes

And next time remove the caliper vs remove the brake hose.

 

When I replaced my brake hoses, I had a full drain of fluid just like you.

I used the 1aauto method, but only bled the brakes.

 

I bled all 4, but the brake light is still on?

 

Dang, so i have to take the master cylinder off?

Yea lesson learned.

 

My brake light had never worked for low fluid so I'm no help there.

I just maintain an eye on the reservoir.

 

Nope, just the caliper (part that holds the brake pads). You can hang it up out of the way without cracking the brake lines open.

You're in good hands with @Tundra2's advice. Good luck!

 

Ok the light went away itself

 

Did you bleed the LSPV after doing both rears?
