What's going on? I got my brembo cross drilled and slotted brake rotors for my back wheels. Well decide to set them up my self. I took my calipers and screw the brake pistons all the way in like in the manual. Them drove around with them and raise my rear wheels again. The crazy thing was that I could turn my wheels ,even with metal stick against my brake padel. Looks like my rear brakes don't work. BUT, if I will put them on the parking brake -it holds whells tight and I could not turn it. Somebody please make sence out of it . Any inputs are appreciated.

Thanks a lot

 

was your engine running while you tried this? I could do the same with the front wheels without the aid of the vacuum. I put a brick ontop of the brake pedal after i put on some new pads to test out if i did it right. I asked my bro why this happened and he said it was cause there wasnt any vaccum.

No, bro. I did not runn my engine, when I was changing them . But I did a drive test (around the block) but both whells are still preety loose.

 

what should I do now? To fix it?
Thanks a lot

 

Try pressing the brake pedal harder. They are set up to use less clamping force in the back than in the front. I believe its like 60%-40% ratio. And you also might want to bleed your brakes because they probably need it.

 

Since the e-brake is cable operated, and the regular brakes hydraulic, I'd suspect air in the rear brake lines.

 

See the thing is that is bleed my brakes before change my pads and rotors.

 

I meant, I did bleed my tires before rotor/pad change

 

rebleed your brakes when you installed the pads you pushed the piston back and may have gotten some air in the lines i recommend a vacuum bleeder
