SS braid lines have zero flex. So will give you rock hard braking feel in pedal. If fluid good, seals in master in top condition, accumulator still has/holds great pressure and calipers re-sealed. One toe on pedal will engage brakes hard. Install some DBA rotors and pads. It will blow-your-mind how hard pedal feels and how much stopping power. Braking will take some getting use to, especial if on ice.
New OEM flex a little, fit perfect and lock-in all as designed by Toyota.
I've had issues with Power Stop. It was years ago. But IIRC, it had to do flare. If a line (flare nut) ever removed for any service, count on replacing that line. The Slee have a better flare IMHO. So I prefer Slee' SS. But neither have the proper lock pin at/to banjo. Or proper hold on knuckles.
There was a set in the market, built with locks and clocked just like OEM. But I had trouble twice with seller. He's listed out of Australia in ebay. But his brake lines, were shipping from China. Than move to Southeast Asia. First set I purchased, one line clocked wrong. Second set one line totally wrong. In both cases he'd ask for pictures, which I sent. In both cases he'd then ask for more pictures, which I's send. In both cases after review pictures statements, he promised to sent a replacement. He'd not send! I'd repeatedly ask for the replacements he promised. He's then asking for me to return first, and on my dime. I did return, and still he'd never sent any replacement. He's either a drunk, on drugs or just an a******!
I'd go with either Slee, if extra length needed for drop down. I just use OEM. Or combination longer drop down (have made) and OEM at caliper. In most cases, the long drop down is not needed. Test is to fully drop rear with use of a jack, see is some slack remains.
Tip: No matter which pads used in fronts. Install the shim kits. The caliper seals curl/roll ever so slightly while braking. As brakes release, the seal rolls back, pulling piston back. The shims clip into pistons and lock them to pads. This pulls pads off disk, reducing heat & increasing pad life.
Note: We've two different size front brake calipers in the 100 series. 98-02 has smaller pistons than 03-07. Order seal kits & shims according.
