I have a 2002 Chevy Blazer ZR-2. I want to replace the rear brake line. What is the diameter plz? Different sights veri from 3/16 to 1/4". Also is there a kit with those two lines pre- made and flarred correctly? A local Napa store to me claimed to have the parts/lines in a kit, had to be ordered, both lines flarred with nuts etc., good price too $27.00, it would take a couple of days to come in. Called today, the guy I spoke with had no idea what I was asking for and said they have no such kit. The good news is that I didn't have to pay first. I appreciate all the help I can get. Hv agr8 day.

 

Not looking forward to it. I believe the hard lines have a splinter above the rear axel. From there it has some rubber lines and the line from the master cylinder to the year axel you make yourself and put double flares on either end. Blessing the abs unit can be fun. Just search and find a thread. I found all the information I needed for the fronts. I’m a first time Chevy owner at 45 and may regret getting the little 2000 blazer for my son. Been busy replacing every original line for every fluid system as well as belts and suspension parts. But it’s a fun little truck and he’s driving classic to school. Even if it is a rust bucket that has been brutal every step of the way.

 

Just did my 2001 ZR2. The front lines are 1/4". The line to the back is 1/4". The lines going across the rear axle are 3/16". Hope this helps.

Be sure to get the correct rubber lines for the ZR2 if your replacing them. Two lines in the front from the hard line to the caliper. Two from the master cylinder to the ABS. Three in the rear, one from frame to axle, two for the calipers.
