Dear All, 

Hope all are fine...

How to solve whoosh sound when I am apply brakes, and break performance also very poor, delay to sopping the car...

Pls suggest how to resolve this...

Check the rubber vacuum hoses from the tandem pump to the solenoid block, vacuum reservoir and brake servo (booster).

 

Be sure to check the hose nipple on the pump, if it's loose apply silicone sealer.  Also check the hard plastic pipe for cracks/splits.

 

Those are the external checks, perhaps the servo/booster has failed.

 

Better ask a mechanic jaldy jaldy!

Thank you Mic...

As u said there was vacuum hose pipe was cut down by Rat I think so, I parked my car native from house agri land... now it resolved... its very smal pipe cut down got big problem...

And brake booster everything fine.... 

Got resolved my self... no mech needed... Jaldy jaldy lol ... 

Very good, I'm glad you found success.
