Brake Fluid or Brake Lines
Hi All,
Just got back from a great day at the track, got almost 35 laps in the beast! Each stint was 15 mins long (almost 10 laps per stint). Managed to beat my best time by 1 second!
Anyway, back on topic towards the end of the stints, I was noticing my brake pedal was getting quite long. In-fact on the last corner of the day it went strait to the floor (at my normal braking point) but the car was carrying way too much speed into the corner & I came off. Thankfully no damage! Fast forward to yesterday, I took it to an indy and asked them to put dot 4 or 5 fluid in it after explaining my adventure. Both mechanic's recommended I get braided lines instead as they would provide better lower temperatures then the brake fluid.
Are they correct or are they just trying to "up sell" braided lines? I thought fluid would be much better then braided lines - I only track it maybe 3 times a year..
Anyone have experience on this subject?

Stainless lines don't lower temperatures, their purpose is to give you better a better pedal feel since they do not expand as much when compared to the oem rubber hoses. I do recommend you getting them if you track at all since it is a one time upgrade. What you need to solve your brakes fading is dependent on your situation, this post will probably answer some of your questions. https://mbworld.org/forums/c63-amg-w...questions.html

I haven’t researched too deeply into this but from what I have read, each scenario is different.
Brake fade with a firm pedal mean you are overheating the pads/rotors and they can no longer stop you.
Good braking with a spongy pedal means you are overheating the fluid or it at least needs to be flushed/bled.
High/rapid pad wear means you are near the pads’ maximum operating temp and should consider upgrading them.
You have at least the second symptom which is either combined with or perhaps caused the first. What was your pad wear like?

Pedal straight to the floor is because of your brake fluid (need higher temp or fresher fluid). Fade is a result of pads (braking too hot for what you have in now). Both are cheap and easy upgrades that make an enormous difference.
