Not usually required but recommended. If the surface of your rotors have any grooves or gouges, then yes definatly have them "turned" at a shop or replaced. If your brake pads are replaced regularly then you should be fine.
It seems like mechanics always turn the rotors no matter what because they don't want to take the time to do the measurements to see if the rotor is in good condition. If they were to take the measurements they could extend the useful life of the rotor. So, if the car is taken to a shop they are going to cut the rotors and turn the drums and give a $200 estimate. The only way to avoid cutting the rotors is to do it yourself.
If it happens right when you are stopping or coming to a slow stop, it is probably your discs cutting into your rear rotors. You need to get them replaced ASAP.
No, The brake line will rupture from excessive rust and heavy to moderate braking. If the rubber line running to the caliper is old and dry rotted then that may also blow out. as for cutting rotors and installing pads, that will not affect anything with the brake lines unless the caliper was not suspended correctly during replacement of rotors. the caliper must be held with a piece of wire to keep tension off of the rubber brake line. allowing the caliper to hang from that line can damage it.
Possible wrong rotors???
25 rotors. Cavaliers have 25 rotors on the car.
no nothing special, your typical rotors will do. no nothing special, your typical rotors will do. no nothing special, your typical rotors will do. no nothing special, your typical rotors will do. no nothing special, your typical rotors will do.
If the rotors are in good condition, not warped, not scratched, then you can replace the pads without turning the rotors. Inspect the rotors carefully.
Sounds like the brake pads - shoes are worn down to medal and cutting into the rotors and drums. Need to pull all 4 wheels off and check the brakes.
after changing rotors
A reciprocating engine is different than when using rotors. Rotors are used in a pistonless rotary engine, using one or more rotors and sometimes called rotary pistons.
Tap on the rotors with a hammer, after removing the tire and wheel and the brake assembly. The rotors will come loose. Slide the rotors off and reverse the process.
