Nugeon 99-01129A rear left brake caliper for the 1990-1993 Mazda Miata is a remanufactured unit that squeezes the pads against the rotor to slow the wheel. Also called a disc brake caliper, this Nugeon brake caliper is a floating design.
A brake fluid leak around the dust boot, a pull to one side under braking or a pad that wears unevenly can mean a caliper is sticking or failing. Before you replace the caliper, rule out a worn pad, a damaged brake hose or a stuck slide as the cause. This listing is one caliper, and both rear sides are normally replaced together.
This caliper is a direct-fit replacement for the 1990-1993 Mazda Miata.
Fit and size
Build and materials
One remanufactured caliper with its bracket, slides, dust boots, caliper and pad hardware, bleeder screw and crush washers; the rear left takes one. Brake pads, anti-squeal shims, wear sensors, the bleeder screw cap and the bracket mounting bolts are not included, so plan on new bolts.
Is this a 1990-1993 Mazda Miata brake caliper for the rear left?
Yes. Nugeon 99-01129A is the rear left caliper for the 1990-1993 Mazda Miata, and the rear right side is a separate part.
Does the Nugeon caliper come with the bracket and slides?
Yes. The bracket, slides, dust boots, pad hardware, bleeder screw and crush washers are included. Pads, anti-squeal shims, wear sensors and the bracket mounting bolts are not.
What size is the piston on this rear left brake caliper?
Nugeon 99-01129A has one steel piston with a 31.67 mm (1.25 in) outside diameter, in a floating caliper.
What can a sticking rear brake caliper look like?
A pull to one side, a burning smell after driving or one pad worn more than the other can point to a sticking caliper, though a hose or slide can cause the same. A shop can test it.
Is the inlet on this caliper a banjo fitting?
Yes. This caliper has a banjo inlet with an M10-1.0 x 27.32 mm port thread, and its bleeder screw is M7-1.0.
