Welcome to Diesel Bombers...

Take the belt off and try to turn the vacuum pump pulley by hand... If it's tough to turn, pretty good sign. Another sign is stiff brakes where you have to stand on them to stop... Lastly, screeching coming from that area is pretty much a sure sign.

the brakes fell ok i guess.
come to think it when i firts got it it was hard to brake but a thought it was the rear brake pads changed tehm it got beter

Is there a fix for that screaching sound?
or is is simple im ****** :ouch:

Just time to replace the vacuum pump. It's not difficult. Three bolts is all...

thanks for the info very much
guess ill buy a new one or, a rebuilt one wich do you recomend?

I think I just bought the reman'd one at Oreilly's when I did mine... Pretty sure it had a lifetime warranty...

thanks ill look in to it?:tu:
$$$ how it go ?

I think it was like 130 bucks or so..
