BRAKE ROTORS, FRONT
'84-87 The front brake rotors are unique to the '84-87 Fiero and were not used in other cars. OEM and aftermarket replacements are readily available.
'88 The front brake rotors are unique to the '88 Fiero and were not used in other cars. GM and aftermarket rotors are available but tend to be expensive. It may be cost effective to move '88 rear rotors to the front. See Brake Rotors, Rear, '88.
BRAKE ROTORS, REAR
'84-87 The rear brake rotors are unique to the '84-87 Fiero and were not used in other cars. OEM and aftermarket replacements are readily available.
If you have an '84-87 Fiero, you can use the front rotor and caliper from a late '80s Grand Am. If you do that you have no parking brake. You can use the rear caliper from an '80-85 Seville with the Grand Am rotor and have a parking brake, but you must fabricate a mount for it.
'88 The rear brake rotors are unique to the '88 Fiero and were not used in other cars. OEM and aftermarket rotors are available but can be hard to find and expensive. Rear '88 rotors can be replaced by rotors from a '93 Cavalier with 2.2 SFI engine at a cost of under $20 per rotor. The Cavalier rotors are slightly thicker than Fiero rotors and may require the brake pads to be reduced in thickness. The Cavalier rotors will not fit the front hub in the '88 Fiero, only the rear.
We have read but cannot confirm that brake rotors for the 1988 Corvette will fit the rear of the '88 Fiero.

BRAKE HOSES
As far as we can determine, no other cars used the same flexible brake hoses (the ones that attach to the calipers) as the Fiero. This does not seem right to us. We suspect that there are indeed other brake hoses that will fit but just have not found them. In fact Aaron Trent found that the left rear brake hose on his '86 GT can be replaced by a left front brake hose from a '92 Honda Accord. Arron had to re-use his old copper washer and banjo bolt, but it worked fine. Thanks, Aaron, for this tip. Note that the '86-88 Fieros used the same left rear brake hose, so the hose from the Honda Accord would fit these three years, not just the '86.
Some of the brake hoses in the Fiero were used more than one year. Using the GM part numbers as a basis, the following Fiero years will swap:
'84 Right front brake hose is uniqueFor the '88 Fiero (sorry we don't have info on other years), the following part numbers apply to the brake hoses:
HOSE AC DELCO # GM # WAGNER # RAYBESTOS # AUTO SPECIALTY # Front, Left 18J668 18032379 F116843 BH38654 HB-80266 Front, Right 18J669 18032378 F116844 BH38653 HB-80267 Rear, Left 18J652 18032363 F120873 BH38638 HB-82346 Rear, Right 18J653 18032364 F120874 BH38639 HB-82347While the above numbers are for '88, note that the '85-88 right front is the same, and '86-88 left rear is the same.
