^^^ agreeing with that. The brakes in my '91 are great. Think back to 1990 or 1991. Lexus released the best sedan ever. Do you think it had sucky brakes? Of course not. If your brakes have any problem at all with them, it is not due to the design. They are supposed to be perfect.

Separate from the issues discussed here, I think people often over-obsess with brakes. They want bigger wheels since they look cool, and then the brakes look too small, and they think they're going to win Daytona this year, and want big brakes to fill in the wheels. Fine, but it does not have much to do with braking necessity. In '92 they did increase the size of the front calipers just in case granny wants to finally win Daytona.

One other thing to consider / look for if you have a feel problem ... brake hoses. I think at about 25 years and 190k miles, one of my brake hoses sprung a slight leak. Luckily I was right on top of it, and replaced all 4 as soon as I noticed the leak. Who knows ... if one had actually not leaked, maybe I would not know they were deteriorating and they would have softened enough to provide the compliance that would result in the "feel" issue that some have. I replaced with rubber hoses, and will not be taking this on the race track. Working perfectly.

Agree with all but not turning rotors.Ive always either turned or replaced drums/rotors.I want brakes at full new specs when I do brakes.On my 67 jeep I did it all but the steel tubes,at 50 years it needed it.

OK,didnt always do truck rotors,pads were simple,4x4 rotors can be a bear.And have to say they worked fine.Not excellent,but fine enough.On jetta rotors are dirt cheap,did them with each pad change

If you want better brake feel, you need to reduce the expansion in the brake lines. Try finding someone who makes stainless braided lines and your pedal feel will get much much better and less spongy.

I did this upgrade on my 93 accord and my brake pedal feel is rock solid with hardly any flex in the lines compared to the stock rubber hoses. Cost me about $110 shipped for a 6 line kit due to its weird design. Techna-fit I think was the brand I used about 8 yrs ago and haven't had any issues since the install.

But I also deleted my ABS system due to a leaking modulator and added a proportioning valve from a rear disc, non-ABS equipped car to help with the brake distribution since the ABS isn't doing the modulation.

But I doubt anyone here is willing to do that unless you're in the drifting scene and transforming the car into something crazy.

On a side note, I ordered some Beck Arnley Sumitomo/Advics OEM brake pads yesterday on RockAuto and will report back on how the pedal feel has changed before and after the pad swap.
