Brake Master Cylinder (i've not heard it called a pump)

If it is a new Master, or a rebuilt Master you are installing, you must bleed the Master before you bleed the wheel cylinders. Otherwise it may not pressurize the lines.

Hi DD

Actually it was the old one that i used earlier also recently put new rubber washer kit, now it is just pressuring and deliver oil for the 1 st outlet(this is just the 1st one which colser to the steering wheel side )is it master cylinder ? i am not getting oil coming out of the other one

Yes, a very common problem. Take it back apart and carefully re-do the parts order. Anything in the wrong place, seal turned backwards or check valve in reverse can cause this symptom.

Then bleed the master cylinder BEFORE you install it. Make sure both ports are delivering pressure.

Hi DD
