Good idea. I was thinking about making one and then got lazy and bought one. On your tool I think you need to round over the master cylinder end of the tools rod more to match the boosters pin, or your tools rod will not quite reach the bottom of the round hole in the master and your measurement will be a bit short.

Brilliant simplicity !

I saw a video where this H tool doesn’t work on a master cylinder with a long snout….what would be an alternative to measure push rod in booster?

Tq so much bro....

Nice :) Think Ill make a similar tool for my next brake booster install. If I undertood you right. The only important thing is for the pipe to be the same legnth as the wood.

I'd like to built one like this , can You help me with the legnth ,thks👍

Will the Baer tool work with my vehicle? i have a 1987 jaguar xj6, 4.2l. will the tool work on this older British car?

Well??? Does it work even though it does not look exactly like the store bought one?

Yea but nothing moved tho on your little tool there bub
