ZHP 3 - A Corner Carver

[cornercarver]

Attempted to bleed the brakes this weekend... The LR bleeder screw was frozen so I'll have to replace it at some point. I skipped that caliper and did the other three. The fluid was definitely old and was a reddish-brown color compared to the gold color of the new fluid. Pedal feels a bit better, but didn't improve as much as I had hoped. Might be due to the small amount of old fluid left in the caliper I didn't bleed, but probably more likely due to the lower grip of the ceramic pads. It's not the end of the world, and hopefully as they wear/bed, the grip and feel will improve.

The front rotors still only show about 2/3 of their area swept by the pads, and the wear pattern is graduated; much heavier toward the center of the rotor - which is also a concern. (The old pads evenly swept 90% of the rotor.) It's the same on both sides, and I'm not sure what's causing this. I may ping the Tire Rack's tech dept...

Chris I have an extra bleed screw for the OE calipers. Let me know if you want it, I can get it from the house this weekend.

If you bleed that last caliper and the pedal feel doesn't improve, that might be just the way it is with those pads you're running. I have the same impression when I sapped out my pads: pedal feel improved but never the way it was with the OEM pads

Thanks for the offer! With my luck the old bleeder screw will snap off, and then it's not worth the effort to drill it out. I'd rather spend that time replacing the caliper. I'll probably get new calipers in the rear at some point, but I've been waiting to see if I stumble upon some miracle Craigslist or eBay sale of 135M F&R calipers that just bolt on without any reverse-engineering on my part.

I've been reading up on the Akebono ceramics; people who have had them for a while say you just have to wait out the 'no brakes' period as they bed, which takes a few hundred miles. Unfortunately 400 miles for me takes several weeks because I have a 3-mile commute and mostly use my wife's car on the weekend.

Sounds like you need to ride to work with your left foot on the brakes for a week. Mindful of drivers behind you, of course.

I think that's more likely to overheat the brakes.

There's no procedure to expedite the bedding process?

I’m no expert on bedding, so I researched it online... This Tire Rack link seems to sum it up pretty well; https://m.tirerack.com/tires/tiretec....jsp?techid=85

Whoa, that’s unique. Much like you, that would take me a very long time to properly bed. Looks like I’ll just stick with the brands that use the normal bedding process.

I typically bed this way....

I did not read the article at Tire rack so they could be very similar.
