I'm a fairly new DIY mechanic and I'm about to attempt my first brake pad replacement on my 2017 Honda Civic. I've watched several tutorials and feel confident about the process of removing the caliper and swapping the pads, but I'm unsure about a few specific details. Should I also replace the rotors if they have a slight lip but no major scoring? Is it absolutely necessary to use a torque wrench when reinstalling the caliper bolts, or can I rely on a good feel with a standard wrench? Also, I've heard conflicting advice about whether or not to lubricate the back of the new pads and the caliper slide pins. What specific products and techniques do you recommend for a safe, squeak-free job?
Reply 1: On rotors — a lip isn’t automatically a red flag, but you should measure to spec. If the rotor thickness is within the OEM minimum and there’s no deep scoring or heat cracks, you can usually reuse with new pads or have the rotor lightly resurfaced. If the lip is pronounced or you notice runout, scoring, or uneven wear, it’s safer to replace the rotor (or have it resurfaced to restore a smooth surface) before the new pad bedding. Keep in mind modern rotors won’t tolerate much extra removal, so check the service manual’s minimum thickness and runout limits before deciding.
Reply 2: Torque and caliper bolts — yes, use a torque wrench. The brakes are a critical system and relying on feel is risky. Install new fasteners if the manufacturer recommends it, torque to the spec in your service manual, and recheck torque after a short test drive. If you don’t have the exact spec, call up a reputable vehicle-specific guide or dealer bulletin rather than guessing.
Reply 3: Lubrication approach — don’t grease the friction surfaces. You want a thin, even film of high-temperature brake grease on the back of each pad and on the edges where the pad contacts the caliper bracket or anti-rattle hardware. Do the same for the slider pins: clean, then apply a small amount of silicone-based brake grease to the pins and bushings. Avoid copper-based compounds on pad backs and pins (they can damage rubber seals and aren’t ideal near brake components). Make sure the hub and rotor are clean and free of grease before reassembly.
Reply 4: Your workflow for clean deformations of complex joints? Is this for mechanical work? No—kidding aside: for a safe, squeak-free install, do a clean job in stages: (1) inspect rotor state and take measurements; (2) clean mating surfaces and apply correct lubricants only where intended; (3) torque to spec and bed the brakes by performing cautious, progressive stops to seat the pads; (4) check for any vibrations or squeal after a short drive and re-torque if needed. If you want, I can tailor a quick pre- and post-assembly checklist based on your car model.
Reply 5: Tips for products — use a high-temperature brake grease (blue silicone-based or equivalent) for pads/pins, and only clean with isopropyl alcohol or brake cleaner. Replace pad shims if your calipers use them. If you suspect the rotors are warped, have a shop check runout with a dial indicator. If you want brand suggestions, share your location and I can point you to reputable auto parts stores or online kits that are well-reviewed.
Reply 6: Want more precise guidance? If you tell me your Civic trim (front/rear brakes, disk size), I can look up the exact torque specs, minimum rotor thickness, and any model-specific cautions and give you a tight, step-by-step plan that matches Honda’s requirements.
