Technical Hydraulic throw out bearings

Had a very scary issue.
Was using a vacuum bleeder on a new install Tilton hydraulic throw out bearing... certainly not the first time...when I was informed loudly that such was a no no!!! It will be damaged.
Huh...first time to hear such.
Anyone else??

Bleeding a T O is not like brakes. The upper hose should be long enough to come out of the clutch fork hole. OPEN the bleeder after you have filled the reservoir, and place it in a cup of the hydraulic fluid you are using making sure it's always kept in the the fluid. Pump the peddle a few times. DO NOT CLOSE THE BLEEDER DURING ANY OF THE PUMPING. Then take the bleeder out of the cup of fluid and close it. The check your peddle. You should have resistance. Check the disc gap. This has worked for us for the last 8 years on our dirt car with 3 different T O bearing brands.

 

I normally just let them gravity bleed.
What reason were you given for not using a vacuum bleeder?

THANX RICH

 

Well here's the deal....I agree with the gravity bleed...been there done that too. With gravity bleed that means the path is open from remote jar through throw out to the catch cup/can or what ever.
Now if nothing has changed and a vacuum is put on the bleeder valve...then a light draw should enhance the free flow....no?
Then remove the vacuum, close the bleed valve and wahla...we have pedal. There has been no resistance.
Modern Drive Line (MDL), warns such activity will **** the seal out of the piston bore.
Never heard of such.
