Brake Upgrade and Spongy Pedal

Well I had it with the OEM rotors which if not run regularily rust and then grove tearing pads. I was changing pads yearly front and back. One rotor before after a rear caliper started to seize and ruined the inside of that rotor.

Well I put on a set of drilled/slotted rotors and new Carbon/Metallic Pads which are support to be very good. Oh rotors are Zinc plated so not rusting non contact areas.

A break-in drive as per the supplier of at least 8 hard stopping stretch from high speed to a fast roll around 20km/hr was needed. I know the pedal will be spongy when things get real hot as they always do with new pads and rotors as the mate together. It all cooled down while I feasted a wing place and gorged myself before heading home braking normally The brake pedal is still spongy and goes down more than I like. I am not sure if I need to bleed the system with fresh fluid or is the Master cylinder packing it in.

Anyone run into this on this vehicle before?

Yep, fresh bleeding usually helps.
Pity, you had chance while discs and pads were off, to clean that rust on calipers and to give them some color and protection paint. Just done the same job yesterday, EBC turbo rotors front, solid premium back and yellowstuff on all 4. Did you check the vanes not wholes pattern, cuz those drilled/slotted are directional? Mine front EBCs according to the manufacturer specs are just in the opposite direction from yours, and it doesn't matter really in EBC's case, theirs vanes are straight anyways not curved inside those discs.
And it depends on pads manufacturer too, the brake-in procedure. Usually it's 200-300km gentle on pedal, no heat, no smoke, to bed rotors as well..
What's your combo?

Not sure about the question but I PM"s the kit info. Looks like mine but Zinc. Black was available but I opted for the shining Zinc. Better suited to my rims as well.

Sorry about my very late response. Yes, got your email. Thanks.
Well, aside of looks, we know nothing about pads quality and used material in production. This could be the issue with all less-known manufacturers for almost anything from the Internet. Especially if it can be find as original/fake on Chinese markets. Beware, it's brakes you're playing with. Hope everything is good now, maybe they need only a proper bed-in procedure.

Well its been a while and yes the brakes and pedal travel has stablized. Braking is good again. The pedal is not hard but I can't say I every recall any PB system with one that is hard. It just seem spongier than normal. Although not done for looks these rotors do look good and should not rust since they're zinc plated.

Yeah painting the calipers is one thing but I have had one already fail due internal issues which caused the caliper not to fully release destroying rotor and the pads on it. Thats all gone again with this change. I expect the needed Bed-in period settled the issue.

Thx for the post.
