Had these installed today. Wow. My brakes were not bad before but what a difference. Sponginess is all gone, confidence inspiring short stops. Locks them up with little effort (compared to before). Didn't touch anything else. And they are not 50 years old!

What's the procedure for replacing - any tips to reduce how much of a mess this makes?

What's the procedure for replacing - any tips to reduce how much of a mess this makes?


I'm going to be doing this soon. I also have a set of Erics new SS lines to put in. But I'm waiting to do it till I can replace to rotors and do a full brake service.

In general, with the car up in the air, and the wheels off, you take the soft lines off one corner at a time, replacing them as quickly as you can. Brake fluid is going to drip and you want to minimize that. Have things prepped and ready to go ahead of time. Put some penetrating fluid on all the clips and connections so they pull out easier.

When done you are obviously going to need to bleed the brakes. I'd suggest doing a complete flush.

And (DWD be damned!) while you are in there - brace up your brake master cylinder so it does not flex the sheet metal its attached to.

Again, prep is the key here. Get under the car and look and see what needs doing. the clips aren't impossible to remove, but they often get a little corrosion and get stuck. I've used a hammer and drift to get them started moving, and a pair of vice grips to remove them once they budge.

If you have never replaced your hardlines... Oof. You may be in for an ordeal. If you have replaced hardlines then they should be in pretty good condition, just go slow and don't strip them out. Penetrating fluid is your friend!

Its not hard, just tedious and could be messy.
