Hi folks just wondering is there anyway to check out the power brake booster to see if it is any good tks.

 

Are you trying to troubleshoot braking issues or a vacuum leak?

 

When I bought my recent project the brake pedal would go to the floor and what brakes I had felt "spongy" to the point where the truck really wasn't at all safe. Once I replaced the booster its all perfectly fine. Not sure if you can check to see if their good, it was very obvious in my truck.

 

I recently had a JY booster that worked perfectly with applied vacuum. Solid. Brakes grabbed hard with little pedal effort.

However, the booster wouldn't release the vacuum and a simple drive around the block resulted in the front brakes almost being locked up... to the point of barely being movable with the pedal matted to the floor.

'Got a remanned booster from RockAuto and all is well.

 

It sounds like you have air in the lines..

 

The Power booster isnt in the truck is there a way to check it out on the bench at all. And tks for the replys they alll help down the rd.

 

Only whether it holds vacuum. I suppose the input rod can be stroked to see if the vacuum is released.

 

Ok tks HIO Silver will check it out and see what happens
