Stainless Steel Braided Brake Lines
TTSPORT stainless steel braided brake lines replace aging rubber hoses with a low-expansion PTFE core, SUS304 stainless braid, and a protective PVC outer sheath. The result is a firmer pedal, more direct hydraulic response, and more consistent feel under repeated hard braking.
Why Upgrade to Braided Lines
Factory rubber brake hoses flex under pressure. That flex absorbs hydraulic force before it reaches the caliper, which translates to longer pedal travel and a softer, less predictable feel. Braided stainless lines constrain that expansion so more of your input goes straight to the pistons.
- Sharper initial bite and shorter pedal travel
- More consistent feel during repeated stops
- Better modulation when trail-braking or threshold braking
- Pairs well with upgraded pads, rotors, and big brake kits
Construction
SUS304 Stainless Braid
Tightly woven stainless steel braid wraps the PTFE core to limit radial expansion and protect against pressure-driven ballooning.
PVC Outer Sheath
Smooth PVC jacket shields the braid from road grime and reduces abrasion against suspension components, paint, and surrounding hardware.
Crimped Fittings
Machined fittings are crimped to the line for a sealed, leak-resistant connection at the caliper and chassis hard-line side.

Length, fitting style, and routing vary by application. Always verify fitment for your specific vehicle and brake setup before ordering.
This product page describes stainless steel braided brake lines only. Calipers, rotors, pads, brackets, rotor hats, brake fluid, and installation hardware are not included unless separately specified on the final order.
Installation Notes
- Confirm line length, banjo or flare fitting type, and thread size against the OE hose before installation.
- Route the line so it follows the original path with no twisting, kinking, or stretching at full suspension travel and full steering lock.
- Use new copper crush washers on banjo fittings and torque to the caliper manufacturer's specification.
- Bleed the brake system thoroughly after installation and check for leaks before driving.
- Inspect periodically for chafe points where the line could contact suspension, steering, or bodywork.
Safety: Brake line installation must be performed by a qualified technician. Do not force a line into position or allow it to rub against moving components. Improper installation can cause brake failure.
Good Pairings
Braided lines are the hydraulic finishing touch for any brake upgrade. They work well alongside performance pads, slotted or drilled rotors, fresh high-temp brake fluid, and big brake kit installations where pedal feel matters most.
Frequently Asked Questions
Will braided lines actually firm up my pedal?
Yes. By limiting hose expansion, braided lines reduce the amount of pedal travel absorbed by the hose itself. The change is most noticeable on vehicles with original or aged rubber hoses.
Are these lines compatible with my brake fluid?
The PTFE inner core is compatible with standard glycol-based brake fluids including DOT 3, DOT 4, and DOT 5.1. They are not intended for use with silicone-based DOT 5 fluid.
Do I need to confirm fitment before ordering?
Yes. Line length, fitting type, thread size, and routing vary by vehicle and by brake setup. Verify the exact fitment for your application before purchase, especially if you are running a big brake kit or modified suspension.
Can I install these myself?
Brake work should be performed by a qualified technician. The system must be properly bled and leak-checked before the vehicle is driven. Improper installation can cause brake failure.
How long do braided brake lines last?
The PVC sheath protects the braid from road debris and abrasion, supporting long service life. Inspect the lines periodically for chafe, cuts, or contact with moving components and replace if any damage is found.

Destroyed in under 10 minutes
Size: 9 in, Color: Large Bone
I bought 2 of these toys, one for my 9 year old great dane who isn't an aggressive chewer, and one for my 6 month old puppy who is average.
In less than 10 minutes both were destroyed and my dane managed to swallow a good chunk.
I wasn't surprised when they both had small holes on the ends and started pulling the stuffing out. The stuffing and squeakers were confiscated immediately, but I let them keep chewing. By the time I came back from throwing the insides away, both dogs had chewed the toys in half and my dane swallowed a chunk when he saw me coming. The puppy was going to do the same thing, but luckily we're working on his "drop" command so he was excited enough for the bigger payout and dropped it.
They didn't just come apart at the seams, the whole toy ripped in half making it too easy to swallow. Neither of them are aggressive cheers and the toys didn't hold up at all. A stuffed animal toy would have lasted longer (and has any time I've allowed it). 10 minutes of playtime is probably too generous , but I'm trying to be fair. If I hadn't been right there watching them, they both would have been able to swallow the whole thing in minutes. Definitely not safe for any amount of actual chewing.

The perfect teething toy for a puppy of any size - apparently indestructible!
Size: 9 in, Color: Large Bone, Size: 9 in, Color: Large Bone
I ordered this product for an overly excitable, destructive corgi chihuahua mix puppy, who was teething. He was a foster and managed to destroy, almost immediately, every toy I had on-hand for him, and toys I picked up at the local pet store. I was very concerned he'd swallow parts of toys, which can lead to fatal intestinal blockages, not to mention extremely high vet bills which I couldn't cover as a simple foster mom. When it arrived, I crossed my fingers that the "Seam Protection - doubled-stitched seams with heavy duty thread" would actually add "extra durability." And I was NOT disappointed! The bone shape of the toy would probably fit comfortably in the mouth of any dog or puppy, as you can see from photo #4. What's coolest about the shape of this toy is the pup can sink all of his or her teeth into it, providing comfort for the entire mouth and not just a few teeth or only one section of its mouth at a time. I was much more experienced as a kitten foster mom, and had had similar difficulties finding teething toys for kittens. This toy is thin and light weight enough that I imagine it could provide relief for little kitten mouths, also, but I didn't get to find out, as my little foster pup chose this as his #1 favorite toy and brought it with him to his forever home. I wanted to know how long it would take before he'd destroy it, though (picture 5 he'd had this Dura-Fused bone toy for a few hours short of one week, and the last photo - you'll see he'd not even undone a small portion of the seam!) Overall I would highly recommend this product for teething babies of almost any species. As far as I could tell it is indestructible. Almost seven days of constant gnawing and he'd not even taken one stitch out, created any tear or rip, let alone, gotten close to being able to swallow the squeaker (always a fear!). I imagine months later, he's still been unsuccessful at ripping/tearing this toy at all. I'd gladly buy again should I foster any dog or puppy - the company lives up to its moniker, Ethical Products, because they've produced a no-frills and apparently indestructible squeak toy which I'd have no fears of leaving with a teething puppy unsupervised. Highly recommended!

Good tug toy
Size: 15 in, Color: Retriever
I have a doberman that shready everything in 2.5 seconds. This lasted a few days so was impressed for the cost. Would buy again as he really liked it.

My dog’s new favorite
Size: 8 in, Color: Squirrel
didn’t expect much for the price but my dog actually loves this thing. It’s tough enough to hold up to regular chewing and the leather gives it a nice texture that’s different from the usual plush toys. He carries it around like it’s his prize. It’s not indestructible and if your dog is a heavy shredder it probably won’t last forever but for moderate chewers it holds up way better than a lot of toys I’ve tried. Definitely worth grabbing again.

Not for gnawers
Size: 11.5 in, Color: Bear
I was hoping this would work for my teenage ACD and save my leather goods from being chewed on.
He gnawed on it quietly I was thrilled. But I had to take it from him within a few minutes. Gnawing apparently equals chewing pieces off.
Not made for chewers or gnawers.
It seemed to be well made, was soft, was actually a fairly good size and didn’t get gross when it got spitty. Just didn’t work out for Captain chaos destructor of all.
