Can anyone tell me if these brakes/calipers are OEM? They don't look like anything special but the car is new to me and idk what the originals look like. Pics attached. How do I know if my calipers need to be replaced too? I was going to measure the rotors, but the rear set is pretty rusty and i want new ones on there anyway.

Also are these a good replacement? I wasn't planning on getting drilled or slotted but these are a good deal for the set ya?

Thanks!

 

That is oem base goodness right their...

I got the sector 27 package from tire rack, it seemed like a good deal to me for $400ish came with new pads and rotors.

 

Did you change calipers? My Z has 92K. Calipers look ok though I won't really know until I take it apart and give em a cleaning. What mileage do calipers usually need replacement?

 

You have factory non brembo brakes.

 

Calipers themselves rarely need full replacement. The piston and seals may need to be replaced periodically (caliper rebuild).

Cannot give you an estimate on how long before that's needed, however, because of so many outside factors influencing the life of the pistons and seals.... weather being A-number-one. If the car is parked outdoors and/or you have inclement weather or snow or salted roads, the frequency is going to much more often than say, living in a California and the car parked indoors.

Also, depends on how the driver treats their brakes. Racing applications or too much brake riding or improper braking all contribute to shorter lives.

Like you said, only way to know is to tear down and inspect.

 

I didn't change my calipers they still function fine, my plan was to get rebuilt ones from a local auto parts store if I needed too.

Z1 also has a brake kit with pads rotors and lines for a good price, and if you wait till thanksgiving they usually go on sale for black friday deals.

 

Yea I think my calipers will be fine. If I change the lines I'll need to drain the brake fluid? My fluid looks pretty new. I don't think I'll need to change it.

 

You will most deff need to bleed the brakes if you change the lines.

 

Big warning***

It's actually a very simple job to change a caliper, install new lines, or change/bleed the fluid - as long as you don't let the system run dry. If you pull off a caliper or a line, put a rubber cap on the line to keep it filled with fluid, and make sure there's plenty of fluid in the reservoir. Once you get air in the system upstream of the calipers, in the ABS pump, or the master cylinder, the Z system becomes a real pain in the *** to bleed. The best way to get a good bleed is to use a pressure bleeder, like the one from Motive Products, and it's a great tool to have for any home mechanic.

Since the car is new to you, it's always a good idea to change all the fluids (and filters, belts, etc.) so you'll have a baseline and know when things have been made up-to-date. Brake fluid absorbs moisture, and it's a good idea to flush it yearly.

As for those rotors and pads you linked, well, they're a crapshoot. Who knows what they are, as an unknown generic brand. Brakes are not the thing to take a chance on. You'd do much better buying a proven brand from one of the vendors here. Centric makes very good rotors that aren't too pricey, and Stoptech makes good budget pads. Check out the vendor classifieds. Make sure you order the correct parts for your car, as the early non-Brembo cars had smaller front brakes than the later ones, but the rears are all the same.
