Replacing brake booster vacuum hose

[NightOwl07]

Hello folks,

I'm currently trying to replace the brake booster switch and hose for a 2001 V40. Hoping for some tips

The short story is that the vacuum check switch snapped in half, I bought a replacement part that comes with the switch and hoses going to the electric pump as well as the engine. The pump hose is simple enough, depress a little clip and the hose comes right off.

I'm not sure how to remove the end that goes into the crank case. The replacement part only has an inch long brass section but the old one will only pull for a tiny bit before it just wouldn't budge. Is there a trick?

Thanks in advance,
Dan

I am about to switch out the booster vacuum hose. Were you able to figure it out?

I was poking around (to see what was up with my brakes) and the valve was clearly busted. That said, the part is tucked away pretty well and it looked like accessing it was going to be a pain. Any advice?

Is this what you are referring to?

Yup, I am waiting for the part to arrive. I learned there different versions depending on chassis, we'll see if I got the correct fit.

I had to do the same thing on mine after the hard plastic part of the hose snapped.

Any difficulty switching the device in and out?

[jefe]

Not that I remember, no, but I had some parts removed from that side of the engine already which may have made it a little easier. Pretty straightforward though.

Yep, eventually it all came together without much difficulty. Off to the brakes now.

There is a sleeve that pulls up and locks the hose when your'e trying to pull it out, you have to push that plastic ring in the grommet back in while pulling the hose out.
