Better Brake Pedal Feel...Tech Tip :)

Like most drivers, you like to go fast and mash on the brakes to stop for those turns. Sometimes the pedal feels sloppy and soft. Sometimes you just dont stop fast enough. An easy solution to that is by upgrading the brake fluid and brake lines. Vivid Racing uses dot 4 Motul Synthetic brake fluid to hold up to the temperatures of aggressive braking. The brake fluid has a much higher boiling point then the stock fluid and is a great solution for street or track use. Combining new brake fluid with steel braided brake lines optimizes the stock braking experience. Factory rubber brake lines flex under pressure causing the brake pedal to feel soft or "mushy" Steel braided brake lines give a firm pedal response and allow for much harder braking conditions to be controlled.

The Agency Power brake lines use CNC machined fittings for a perfect fit to the stock caliper and have a smoke covering to protect the steel braided part from wearing.

So at a total cost of around $140 in parts, you can improve your braking greatly over stock. There is always new pads or big brake kits, but for the dollar, this is a good mod. That is my recommendation for the day!









Agency Power brake lines can be found here at

Why Motul and not Castrol SRF?

We always use the Motul. In our race cars, street cars, and it hold up to the test. Never a issue. Never boiled it. We run it in a big brake installs with StopTech, Rotora, and Brembo. We have put it to the test time after time at Phoenix International Raceway. $14.99 a bottle, its worth it!

I used to go with ATE Gold when I did a lot of track stuff but have switched to Castrol SRF since it doesn't need to be bled/flushed as often. Pretty much leave it alone for a year...but it does cost $$$ - about $70/liter.

We are fixing the pic and it is actually Dot 4 fluid. But here is the link to buy it online. Check in 30min for extra info.

Not to argue but - did the lines, use the $70/liter stuff, also added GT2/3 brake ducts- still have stock Pagid (I think Blue) & rotors - no difference in tt brakes. Still mushy at Sebring. tt has a brake boost that helps make the pedal "mushey" for the street (don't need big leg muscles), GT2 does not. GT2 has better feel on the track. Anyway the mods (lines/fluid) did not hurt - just did not produce any great results at the track.

Sorry - Do not remember the brand but very nice set - no cheaply made crap - could have been this brand. Shop that does my work is excellent and preps track and DE cars all the time - this is not a one time thing for my brakes - at first I thought I had a problem - I don't. We always flush after every event too @ $70/liter! My point is new lines are good, fluid is good, system is good - just folks should not expect miracles w/o serious upgrades. tt's are heavy, factory brake boost is to high for track, GT2 set up is better. We (tt's) loose brakes all the time at Sebring w/ just the mods you are talking about - only guys who don't, are going slow or have much more expensive upgrades or move to "better" pads/rotors/brakes and they sound like crap on the street. If you have some bleeding "secret" I'm all ears and am certainly willing to evaluate and possibly give it a try (we are not getting air in and like I said the fluid is not old).
