Stainless Steel Extended Front & Rear Brake Lines From Mudify For 2nd & 3rd Gen (2005-2023) Tacoma: Detailed Install Guide, Review & Overview
If you’re lifting your truck (or already lifted), you need to consider replacing your brake lines. Especially the rear ones.
A stock Tacoma or maybe one with a small lift would be fine with the factory brake lines. Once you lift beyond 2″ though, the OEM brake lines won’t cut it as you run the risk of overextending and tearing them. With extended stainless steel brake lines, you get a firmer brake pedal feel, more durability, and peace of mind when you start flexing out your suspension. Even mid-travel setups can benefit from improved brake feel and response.
The Mudify extended brake lines for 2005-2023 (2nd & 3rd Gen) Tacomas install with ease. The installation we’re covering in this article is on a 3rd Gen Tacoma.

Step 1. Place Rear Axle On Jack Stands + Remove Tires
To make the extended brake line installation easier, you will want to jack your truck up for more room to work underneath it. I lifted my truck with a floor jack then set my rear axle down on a set of 3-ton jack stands.
After I got the truck placed on the jack stands, I removed both of the rear wheels again for more room to work around the truck.
The last thing I did to prepare for the rear brake line install was to drop down my spare tire (if you have one mounted under the truck). Dropping the spare tire will give you a lot of headroom that you will thank me for later when you are working up under the truck.
Step 2. Loosen 10mm Brake Line Fitting
Both of the rear brake lines that we will be replacing are going to be on the driver’s side of the rear axle. Once you locate the rear brake lines, start off by using your 10mm flare nut wrench to break loose both brake line nuts. Don’t loosen these nuts too much or you will have brake fluid leaking and making a mess.
The brake lines will have a 10mm nut on each end so you will have a total of four nuts to loosen. The two nuts in the photo above are the bottom end of the factory lines and above you will see two more nuts at the top half of the factory brake lines.
Step 3. Separate Brake Lines From Brackets
For this step make sure you have some patience. In my opinion, this was the most difficult part of the installation, so if you can get through this part, then you can easily get this project done.
Using the 30-degree push pin pliers, you will need to pinch the U-shaped brake line clip as you see in my photo above. When you have a good hold of the clip you need to pull it off of the brake line bracket. This clip is pinched between the brake line bracket and the brake line so it’s on pretty tight.
On the top half of the brake lines, there will be two more U-shaped clips holding the brake lines in place. The top two U-shaped clips are more difficult to remove due to the tight location.
Step 4. Remove Factory Brake Lines
Once all of the U-shaped brake line clips have been removed you can unscrew the 10mm bolts that connect the hard brake lines to the soft brake lines. As soon as you separate both of the soft factory brake lines, fluid will start to leak.
At this point, you can either hurry up and get the new lines installed before you lose too much fluid or you can plug the hard lines on the top half to stop the brake fluid from flowing. I purchased a silicone rubber plug kit on Amazon and I used these plugs to stop the fluid from running out while I finished removing the factory lines.
Step 5. Attach New Extended Lines
If you choose to get the silicone plugs you can work at your own pace. However, if you don’t have plugs, you will need to work fast to conserve as much brake fluid as you can. These lines install in the same fashion as the OEM ones.
Tip: I choose to connect the bottom first, then do the top. If you start at the top and then go to the bottom, you might get brake fluid running down the new extended line and getting all over.
After you have the new extended brake lines installed, you need to tighten the 10mm nut from the hard lines to the new extended lines.
Using the 10mm flare nut wrench and a 3/4″ wrench, you can tighten the brake lines so there are no leaks and the system is secure.
Step 6. Install Retaining Clips
To finish, you need to install the new U-shaped clips that come with the extended brake lines.
Make sure the extended brake line is pressed up flush against the brake line bracket. Then you can slide the U-shaped clip into position.
To properly install the U-shaped clip, use a hammer to gently tap the clip down in between the hard brake line and the brake line bracket.
You will keep tapping the U-shaped clip until it is flush with the top edge of the brake line bracket.
A pro tip that I learned (from Brenan over at Trail4Runner) is to get the top U-shaped clips installed where you can use a small C-clamp.
I found this to be very helpful since you can see the room for a hammer above that bracket is non-existent.
Step 7. Place Front End On Jack Stands + Remove Wheels
After you have the rear end all back together and on the ground, you can lift up the front end so you can move to the front extended brake lines.
The front extended brake line removal and installation is going to be very similar to the rear end so I won’t go into too much detail.
Step 8. Remove Factory Front Brake Lines
Just as we did on the rear lines, the top end and bottom end of the soft brake lines have a 10mm nut that you need to break loose.
Use your 10mm flare nut wrench to loosen the nut on both ends of the factory line.
Use 30-degree push-pin fliers to remove the U-shaped clips on both ends of the line. These clips are the same exact clips as the rear brake lines. Be patient and take your time trying to remove these clips.
After the clips have been removed, you can finish completely unbolting the 10mm fitting. Just like the rear brake lines, as soon as these nuts are completely loose, you will start to have brake fluid flowing out of the lines, so you need to work quickly or use plugs.
Step 9. Install New Extended Lines
Attach your Mudify extended brake lines to both the top and bottom portions of the factory hard lines.
Hand-tighten both ends of the 10mm nuts until the brake fluid stops dripping from the brake lines.
After the soft and hard brake lines have been connected, you can install the U-shaped brake line clips to the brake line bracket. Luckily for the front brake lines, you use a hammer on both the top and bottom clips. Gently tap both of the U-shaped clips into place until the top of the clip is flush with the top of the brake line brackets.
Step 10. Bleed Brakes
The top of the brake fluid reservoir will tell you what brake fluid your truck takes. Toyota says DOT4 is acceptable but it’s recommended to use DOT3, which is what I used.
To help with bleeding the brakes, you can buy this brake bleeder bottle on Amazon as I did. Or, you could make your own.
I liked this bottle because it has a magnet attached to it, so you can stick the bottle to a metal surface, which is good if you’re doing a single-person brake bleed.
Proper Brake Bleeding Order
- Passenger Rear
- Driver Rear
- Passenger Front
- Driver Front
This brake bleeder bottle comes with a clear tube that attaches right to the brake bleeder nipple. After you attach the clear tube, you can use a 10mm wrench to open the bleeder value. Once the brake bleeder valve is open, you can start to pump the brakes to remove any air bubbles from the brake lines.
Make sure you check your brake fluid reservoir each time you bleed the fluid, do not let the fluid level go below the brake fluid low line.
If you plan on messing with your suspension, this is your sign to buy a set of new extended brake lines. You can hit the trails and let your suspension flex without the worry of having added stress on your lines.
Another benefit to adding these extended brake lines is the upgraded quality over the factory soft lines. The factory soft lines are made of some type of silicone or rubber while the Mudify extended brake lines are made out of multiple layers of stainless steel. The stainless steel hoses are wrapped in two layers of woven nylon braided rubber for additional protection.
For the price and benefits that extended brake lines provide, every Tacoma should have them. The installation is also fairly easy for anyone to do has basic mechanical skills to remove a tire and turn a wrench.
