Hello everyone.

Will stainless brake lines and high performance brake fluid give me a firmer brake pedal? My other sports cars have firm, hard brake pedals and I’d love for my GS to have a firmer brake pedal.

Thanks in advance.

The rubber lines have an internal nylon weave that prevents them from expanding, maybe a little at the microscopic level, but probably not enough to notice a difference in brake feel compared to stainless steel braided lines. I doubt changing the brake fluid will make a difference, unless your brake fluid is visibly dirty and old. Really the only way to get a heavier brake pedal might be to mess with the mechanical part of the brake pedal, but I would highly recommend not doing that.

If you want to upgrade your brakes change the pads to a more grippier one, but that might cause other problem like squeaking when they are not warmed up.

If your set on doing these changes I say go for it and report back to this thread with the results.

Are your rotors worn out?
After replacing the pads & rotors on my older car, pedal response improved a lot.

1st step is to bleed the brake fluid to make sure there is no air bubbles in the brake line system

Stainless brake hose lines are only beneficial on the track. As others have stated, start with a proper fluid flush. I like pressure bleeders on a low PSI setting.

Have you done any brake jobs lately? They should feel firm with or without stainless steel lines.

Most cars I've installed stainless braided lines on had a noticeably "firmer" pedal. I haven't replaced them on my GS, but my pedal does not feel soft at all. So if your pedal is feeling different from before, it may need servicing. If you want it to feel more firm, the lines may help on a healthy braking system.

New Pads, New Rotors (New Thickness), Proper Bleeding, and Braided lines. The Rubber lines expand under pressure. = A Firmer Pedal.
