Removing the brake pads of a Crown involves the following steps: 1. Remove the tire and loosen the caliper mounting bolts. 2. Take off the caliper and release the brake pad clips. 3. Remove the brake pads and use large pliers or a specialized piston-pushing tool to retract the caliper piston. 4. Install the new brake pads, secure the clips, and reassemble the new components following the original steps. Information about brake pads is as follows: 1. Brake pads, also known as brake linings, are the most critical safety components in a car's braking system. The effectiveness of all braking is decisively influenced by the brake pads. 2. Brake pads (brake-lining) generally consist of a steel plate, an adhesive heat-insulating layer, and a friction block. The steel plate is coated to prevent rust, and the coating process is monitored using an SMT-4 furnace temperature tracker to ensure the temperature distribution during coating meets quality standards.

To remove the brake pads of a Crown, you need to prepare a jack, a wrench set, and a pry bar. Ensure the vehicle is turned off and parked on level ground during operation. Loosen the bolts first before lifting the car body, and place a safety support under the car when removing the tires. After removing the caliper mounting bolts, do not let the brake hose hang; use a pry bar to push the piston to remove the old pads. Before installing new pads, remember to clean the rust on the caliper slide rails and apply copper-based lubricant to the metal backing plates and shims to avoid noise. Finally, check the brake fluid level and pump the brake pedal a few times to restore pressure, otherwise, driving without brakes is dangerous. Regularly checking the brake pad thickness can prevent issues like seized components.

I just replaced the front brake pads on my Crown last week. First, loosen the bolts, jack up the car, and remove the wheel. Note that the caliper has two 14mm hex bolts. After removal, don't force the brake pads out; use a C-clamp to retract the piston, otherwise the new pads won't fit. The brake pad retaining clips on the old Crown are particularly tricky—you need to use needle-nose pliers to grip and rotate them 90 degrees to remove them. When installing new pads, make sure to distinguish between the inner and outer sides, with the anti-noise shims facing outward. Don't apply regular grease as it can corrode rubber. After reassembling everything, lightly press the brake pedal until you hear a click to confirm successful reset. Test the brakes at low speed before hitting the road to avoid hard spots.

The challenging part of removing Crown brake pads lies in handling the caliper piston. After removing the tire, disconnect the caliper bolts and use a specialized piston retraction tool to press it in by rotating clockwise. Without the tool, a large C-clamp can be used, but it may easily damage the dust boot. When removing the old pads, inspect the guide rails for wear and sand the track grooves with sandpaper. Before installing new pads, clean the rotor surface of oil stains—I prefer using brake cleaner sprayed on a cloth for wiping. Remember, if the caliper piston isn't fully retracted, it can cause brake drag. After installation, the wheel should rotate easily by hand to qualify. It's advisable to have an experienced person supervise when doing this for the first time.

The disassembly steps are actually quite simple: loosen screws → jack up the car → remove the wheel → detach the caliper → take out the old pads. The key lies in the safety details. I used the hydraulic lift at the repair shop; a home jack requires safety stands. For the Crown's rear wheels with electronic parking brakes, a diagnostic tool is needed to retract the motor—forcing it will damage it. When pressing the piston back, it raises the brake fluid level in the reservoir, so remember to remove some fluid to avoid overflow. The iron dust from the old pads must be thoroughly cleaned, or the new pads will squeak. Finally, tightening the bolts with a torque wrench according to the repair manual is the most reliable.

Apart from the disassembly process, I'm more concerned about brake system . When removing the caliper, check if the guide pins are stuck, pull them out and reapply special silicone grease. Rotors must be replaced if thickness falls below 21mm - don't cut the wear sensor wire on genuine Crown brake pads. After installing new pads, don't hit the road immediately - perform low-speed repeated braking to bed in the pads, and avoid hard braking for the first 20km. By the way, remember to change brake fluid every two years as moisture contamination can corrode pistons. The whole process saved me 600 in labor costs, though I got three cuts on my hands.
