Just got some brembo blanks for my front rotors. I swapped everything just like the write up said in the 4th gen faqs but the last peice to the puzzle is what is stopping me from finishin... The piston wont fit back over the rotor? I dunno what im doing wrong. I measured the thickness off the stock and aftermarket rotors and the stock one is slighty bigger like half a mm. So fitment shoudlnt be a problem. I took everything off and put the stock stuff back on and tired again. Like the problem is the piston isnt sitting flush against the pads like one side will fit on and the other wont. I used a rubber hammer to tap it on but all it did was just scrape my brake pads. I didnt replace the pads cause they were just replaced a month ago with hawks. So whats the problem here??

 

did you push the piston in as far as it will go or did you just lift the caliper off & not push it in at all?

 

Yeah, agreed with the post above. Its sounds like your pistons are not fully compressed. Try a c-clamp to compress the caliper.

 

didnt push it in... Gonna do it right now will keep you guys posted

 

so compress the caliper?

 

Compressing the caliper is pushing the piston back. If your piston is totaly out of your caliper, then you have bigger problems.

 

i have a feelin it might be ill check

 

if the brakes fit & worked fine b4 you changed the parts, then I wouldn't think the piston was "all the way out". as "max out" said get a C-clamp to to completely push the piston back into the caliper so it can slide down over the pads. all it takes is just a little of the piston to stick out to cause a "no fit" situation. if you don't have/can't get a c-clamp then use a large channel lock pliers to squeeze the piston back.

 

gonna try that

 

heh, just be happy your not stuck with your rear calipers. Oh and make sure to rebleed your lines to ensure their isnt any air in them.

 

stuck with my rear calipers you mean?? yea im gonna rebleed them got SS brake lines

 

Yeah, they are a bit tricky to compress compared to the fronts. They have a "spin" out type piston (not sure of the correct name). The reason for them being that way is that it will apply preasure more evenly, or so ive been told. Also good idea going with the SS lines, and good luck to ya.

 

didnt get a chance today... My friend came over and we were just cleaning up the grounds but one problem led to another and the car wouldnt start replaced fuel pump but my cuz is gonna help me sometime this week will keep you guys updated

 

dont forget to take the cap off the master cylinder and possibly a towel around the area so when the piston is pushed in the fluid doesnt spill in your engine bay.
i got brembo blanks too and for some reason (with brand new nissan pads) they still wore like ****.

 

wirelessdude -- here's a tip - loosen the bleeder screw *before* you press the pistons back in. that will push any dirty brake fluid in the caliper's fluid cavity out the bleeder hole, and not back into the brake lines.

then press the brake pedal slightly to push the piston out 1/2 way again (don't go too far), and then push it back in again -- do this a couple times, it ensures the caliper is not sticking. sometimes dirt can get in there and cause it to stick, but if you "massage" it you can help prevent any problems.

after that do a complete brake fluid flush. this basically involves bleeding the entire system several times until you push about 2 quarts of fresh fluid through. this should be done every 3 years.
