OP, you have air in the lines. Try gravity bleed at this point. Don't let MC get low. No pumping, just connect a bleeder hose to each caliper, and let it drain.

You can also do the press in caliper piston too, with bleeder loose. Also tilt caliper around slowly so any air trapped in a cavity can slip out.

Its ironic that people buy ss lines for better brake feel, and often end up with worse.

I concur. Sounds like there's still air in there. Gravity bleed is the best way to go. Run 1/4 qt of fluid through each line to be sure. I usually will use a whole quart for a full bleed.

3) Test drive, awful pedal
4) Start car, drive the front wheels up onto some wood or jack the car up to raise the nose 4-5", fully depress brake pedal, block it fully depressed with a 2x4, shut off the car, disconnect negative battery terminal
5) Wait 12 hours, unblock pedal, reconnect battery, pedal got 80% better
6) Drive for 20 min, get some good heat in the brakes, multiple ABS engagements
7) Rebleed all 4 corners, pulled about a 1/2" air bubble out of each rear
8) Repeat step 4
9) I repeated step 6, 7, and 4 again for the hell of it, didn't get any air out during the bleed.

Now I couldn't be happier with the pedal feel.

Compliments to Billman for the pedal "blocking" procedure.
I should note that all bleeding in the procedure above is gravity bleeding***

Hi,

Thanks for the all info.

I have found a leak in my front right where the banjo bolt is. Found some spots of fluid on the inside of the rim...

Will need to sort this out first before doing the methods suggested.

Did you use new crush washers whe you installed the line?

Raising the nose helps evacuate air to the master cylinder.

To elaborate. Air rises (its lighter than the fluid). So raise the end of the car you are trying to bleed, higher than the other end of the car. Any air in brake lines, etc, will have more incentive to find their way up and out the bleeder valve.

I used the new washers that came with the kit. I've tightened it more and in the last 24 hours and there doesn't seem to be an drips on the inside of the rim but will check more thoroughly over the weekend.

One more question (unlikely lol) in regards to bleeding since my car is RHD. I still follow the below order?

Master Cylinder is on Drivers side

Front Passenger Side
Front Driver Side
Rear Driver Side
Rear Passenger Side

Cheers

What is this float sensor you talk about? Is it that cylindrical thing inside the reservoir?

I've already put about 3/4 of litre through it
Sounds like you ended up with air in the system. One pump with the fluid level too low (sucking in air) and you'll have quite a fun time re-bleeding trying to get the air back out. As far as your light coming on, I can almost guarantee your fluid level sensor is being triggered... either there's a puddle of fluid under your car someplace or you forgot to refill the reservoir. Also remember, you can introduce air into the system to some extent when at the bleeder screw itself (if you're not using check valve speed bleeders that is). Did you do this brake bleed job yourself or with a friend? Takes two people who have familiarized themselves with the brake bleed procedure to pull off a good brake bleed.
