MASTERCOOL 71100 ISO Metric 💣 Bubble Flaring Tool Set in Black Review

I work as an auto technician and this is a great product to have in your toolbox. Most vehicles on the road today have ISO metric fittings. I have used Mastercool products before with no complaints.

If you need to make a bladder flange, you need to buy this. I had to find out a lot more about bladder flanges than I wanted to know but the local dealerships are clueless and providing misinformation. Skip to the end and just buy this tool and save your time and hassle.

Re-done all the brake lines on my 2001 Dodge Intrepid, all bladder expanders. No leaks! Practice before you do the right things. I suggest you use copper alloy brake line. I used steel and copper which are easier to work with.
