Which rotors to buy?

[Milkshke07]

My boyfriend has a 91 SHO Plus and wants new front rotors cause the left brake is grinding and he wants to get a new pair instead of just some new pads. So does anyone know which ones to choose? The ones made before February 91, or after?

Welcome!

You will have to check the build date on the sticker on the driver's door to determine when it was built.

most likely, when u change the rotors, u also need to change the pads...

If the brake sare grinding, he will definitely need both new pads and rotors. I have a January, 1991 vintage SHO and have had very good service from the $18 AIMCO rotors from AutoZone and the (approx.) $30, 4214S, Performance Friction Carbon Metallic pads also from AutoZone. The cool thing about the pads is that they not only grip great. but they come with a lifetime replacement warranty from the 'Zone. You will need a Torx 40 socket to remove the caliper pins and a caliper spreader or C-clamp to compress the piston. Also apply silicone grease to the slider pins after removing an cleaning them. Once you have done the SHO's front brakes, you will probably be able to repeat the job in less than 45 minutes. Simple.

Is there only one failing rotor?
You talk in plural, but say it is only the left front.....
Turn the rotor if it is OEM, save it if you can. OEM pads are best (IMHO). You do not need to replace rotors in pairs, so if it is one rotor fading, turn it and put it back on...pads should be replaced, since they would be pretty shot anyhow. The caliper piston slider pin should be lubed, they are known to be temperamental on Gen I's...and they are expensive if they seize up. There is a tiny little rubber bellow, called a boot that should routinely be inspected for pin holes and slashes that leak out the **** for the pin, and grit can enter here and cause you headaches with the calipers too, so look for it often, just like torn CV Boots that cover the ends of the tie rods and hold the grease for the hub bearings underneath..
Good Luck and let us know more....
