Chase Bays rear brake hard line delete

[othatseric]

Thinking of using this part instead remaking all the hard lines and buying all the tools for the refresh job. Has anyone ever used this? Hows it holding up etc.

thanks!!

While not exactly what you're looking for, I had the rear feed line develop a leak just ahead of the T block last year. Luckily I had the subframe dropped for some other jobs, so it wasn't as soul crushing as it should have been to find the leak wasn't the block itself.

I decided to redo the other two smaller hard lines while I was there; which while having never done that before felt like it took way too long. After spending the time for the two lines I decided there was no way in hell I was going to remake the long feed line, patched it up and just set the car aside until I could come up with an answer.

I just purchased the Chase Bays kit and will be tackling that along with some other projects here in the not-to-distant future. For what the kit costs I felt like it greatly outweighs the frustration with having to bend and install a hard rear feed line.

This looks interesting.

Long runs of soft line aren't used from the factory because they can increase sponginess in the pedal, especially over time. Same reason we don't do it in the race cars.

That's what my concern is with reading about that product. How is the pedal feel with this?

I've never done it for the reason I stated.

so far it feels great, feels quite a bit better than the stock lines.

For plain rubber lines, I could definitely see this, but with braided steel reinforced teflon lines, I'm not sure you could feel a difference, at least on a street car.

That being said, I'd worry about durability over time. Other than rust, steel lines should be a lot more durable than plastic lines, even if they are reinforced with braided steel. And if you are worried about rust, go either stainless or copper-nickel.

At the end of the day though, either option will work.

Fingers crossed i guess...lol

Reviving an old thread here, any feedback on this product after install? Found a leak in my main rear line along with corrosion throughout.

I would suggest getting nickle copper brake line and replacing the stock line. Nickle copper is softer than steel line making it easier easier to bend and make fittings for. The material in the line resists corrosion much better than steel. And its much cheaper than the chase bays part.

I’m not sure why the chase bays product would be more special than any other stainless soft line product. You’re replacing a brake hard line with a usable life of thirty years with a brake soft line that has a usable life that is much less.

It’s worth noting that the ONLY brake lines that I have ever had fail for reasons other than extreme age are braided stainless crimped lines. It’s much harder to get a good crimp on a braided line. You’ll note that a lot of SpecE30 guys have gone back to OE rubber soft lines due to braided line failures.

They also sell a kit that replaces the factory dual circuit master+booster with a single circuit master...... because it looks better?
So you can probably assume they aren't aiming for oem levels of safety.

A few of their products certainly make me question their thought process for products. They make a lot of products seemingly only because nobody else made one. The single master and these full flex lines are two good examples.

Flex lines expand more than hard lines period. The material of the braiding doesn't change this, but can make it better or worse just as overall quality of the hose does. You will have more sponge with these than with good hard lines.

The lifetime of a brake hose is also like a factor of four shorter than a hard line, so you're going to be facing replacement again sooner.

I don't have evidence but I imagine the probability of failure would be higher with this setup as well.

The single master is also terrible from a probability of failure perspective, even before you get into QC considerations with aftermarket master cylinders.
