If you're restoring or rebuilding a 1967, 1968, or 1969 Camaro or Firebird, replacing the brake lines is one of the most important jobs on the list. But it's also one of the most common sources of confusion when ordering parts.
The biggest mistake people make? Ordering a brake line kit before knowing which proportioning valve they're running. Get that wrong and the kit won't fit — or worse, it won't work correctly with your brake system.
This guide covers what you need to know before you buy: how your proportioning valve affects which kit you need, what's included in a pre-bent brake line kit, the material options available, and a general overview of how the lines route on these cars.
Why Your Proportioning Valve Matters First
Before you look at any brake line kit for a 67–69 Camaro or Firebird, you need to identify your proportioning valve. This single detail determines which kit is compatible with your car.
There are three common scenarios:
Adjustable proportioning valves — These are typically used in custom or upgraded brake setups where the builder wants to fine-tune front-to-rear brake bias. The line routing and port locations on an adjustable valve differ from the factory-style brass valves.
Brass proportioning valves (PV2 or PV4) — These are the valves that come with many disc brake conversion kits. The PV2 is for two-wheel disc setups (front disc, rear drum). The PV4 is for four-wheel disc setups.
Factory proportioning valve(s). If our brake line listing from The Stop Shop says something like "Fits 1969 Camaro with factory disc brakes" then we are assuming that this car rolled off the factory line with disc brakes and you are still using the factory valve or valves.
The Stop Shop makes pre-bent brake line kits specifically designed for each of these configurations. If you're running a disc conversion kit that came with a brass PV2 or PV4 valve, you need a kit built around that valve's port layout. If you're running an adjustable valve, you need a different kit entirely. If you have the factory valves (or blocks), then you need a set specifically made for those.
Bottom line: identify your valve before you order. If you're not sure which valve you have, call or text The Stop Shop directly. Getting this right upfront saves time and avoids a return.
Two-Wheel Disc vs. Four-Wheel Disc: Which Kit Do You Need?
Once you know your proportioning valve, the next question is your brake configuration.
Two-Wheel Disc (Front Disc, Rear Drum)
This is one of the most common setups on 67–69 Camaros and Firebirds. Many owners upgrade to front disc brakes while keeping the rear drums. If this is your setup and you're running a brass PV2 valve, you'll want a kit built for that two-wheel disc configuration.
Four-Wheel Disc
If you've done a full four-wheel disc conversion, you'll need a kit designed for the PV4 valve. These kits account for the need for shortened rear disc brake lines since instead of running all the way to wheel cylinders, they run to the hoses that come off the new rear calipers. We shorten these lines by approx. 8" per side to account for the hoses
Knowing your configuration before you order ensures the pre-bent lines will match your hard points and reach the correct ports without modification.
What's Included in a Pre-Bent Brake Line Kit
A complete pre-bent brake line kit for the 67–69 Camaro and Firebird typically includes all of the hard lines needed to run from the master cylinder to the proportioning valve, and from the proportioning valve out to each wheel. The lines are pre-bent to match the factory routing of these specific vehicles, which means less time under the car with a tubing bender and fewer chances for error.
Each line comes with the correct fittings already installed on the ends, so you're not sourcing fittings separately or trying to match thread sizes at the parts counter.
This is a meaningful advantage for anyone doing a full brake line replacement — whether you're starting from bare metal on a restoration or replacing lines that have corroded beyond use.
Stainless Steel vs. Plated Steel: Which Should You Choose?
The Stop Shop offers these kits in two materials. Here's a straightforward breakdown of the difference:
Stainless Steel Brake Lines
Stainless steel lines are the premium choice for most restoration and performance builds. They resist corrosion far better than plated steel, which matters on a car that may see decades of use. Stainless lines also hold up well in environments where road salt, moisture, or humidity are concerns. For a car you're putting serious time and money into, stainless is the long-term investment.
Zinc Plated Steel Brake Lines
Plated steel lines are a solid, cost-effective option for builds where budget is a priority or for a driver that won't be exposed to harsh conditions. They meet the same fitment requirements as the stainless kits and are a practical choice for many applications.
Both options are manufactured in the USA — which is a core part of how The Stop Shop operates. If you're unsure which material fits your build and budget, it's worth a quick call to talk through the options.
General Line Routing on 67–69 Camaros and Firebirds
While every build has its own variables, the general routing on these cars follows a consistent path. Lines run from the master cylinder (typically firewall-mounted) down to the proportioning valve mounted next to the master cylinder. Most of our sets are made for power brake vehicles (with a booster). From there, lines run rearward along the frame rail to the rear axle, and forward to the front wheels.
Pre-bent kits are designed to follow this factory routing, which means the bends are already in the right places for a clean, professional-looking installation. You're not trying to adapt a universal line to fit — the geometry is already done for you.
If your car has been modified significantly from stock, or if you're unsure about routing, The Stop Shop recommends confirming your setup before ordering. Their team can help you work through fitment questions directly.
Common Questions Before You Order
Can I use one of these kits if I still have the original factory proportioning valve?
These kits are designed around the adjustable valve and the brass PV2/PV4 valves that come with disc conversion kits. If you're running the original factory valve on an all-drum car, that's a different configuration. Contact The Stop Shop to confirm compatibility.
Do I need any special tools to install pre-bent lines?
Because the lines are already bent, you won't need a tubing bender for the main runs. You will still need a line wrench set to properly tighten the fittings without rounding them. A flare nut wrench is the right tool for this job — not an open-end wrench.
What if I can't find a kit for my specific setup?
The Stop Shop has a program where you can send in your original lines and they will reverse-engineer and fabricate a custom stainless set from your originals. This is a useful option for unusual configurations or heavily modified cars.
Replacing the brake lines on a 67–69 Camaro or Firebird is a straightforward job when you have the right kit. The key is doing the homework before you order: know your proportioning valve, know your brake configuration, and choose the material that fits your build. Pre-bent kits eliminate most of the guesswork and give you lines that are ready to install without modification.
If you have questions about which kit is right for your car, The Stop Shop team is available by phone or text at 614-557-3442, or by email at info@thestopshop.com. They'd rather help you get it right the first time than deal with a return.
