2000 Toyota Echo Parts Questions & Experts Answers

• Q: How to service and repair the brake caliper on 2000 Toyota Echo?

  A: The service work on brake calipers starts with using a screwdriver to remove the set ring and cylinder boot. Start by placing cloth between the piston and caliper then utilize compressed air to remove the piston from its cylinder position while keeping your fingers always behind the piston. Pull out the piston seal from the cylinder using a screwdriver after the procedure. To check pad lining quality use a ruler and confirm pad thickness since 11.0 mm (0.433 inch) stands as standard while 1.0 mm (0.039 inch) becomes the minimal limit thus pad replacement is necessary for either standard or substandard lining conditions. Measuring the disc size with a micrometer reveals its standard length at 18.0 mm (0.709 inch) while the minimum length should be 16.0 mm (0.630 inch) and if these specifications are met the disc requires replacement or if badly damaged or unevenly worn it needs grinding on a lathe. The disc runout should be checked with a 0.39 inch (10 mm) long dial indicator at the edge to ensure the measurement is under 0.0020 inch (0.05 mm) maximum runout; if the runout exceeds the limit check for axle bearings and hub runout then perform disc adjustments or grinding. To modify the debonding reduce torque on the knuckle mounting bolts and torque plate before you detach hub nuts and install the turned 1/4 disc on its hub. Tighten hub nuts to 88 Nm (900 kgf-cm, 65 ft. lbs). Repetitive procedures should be followed to install the disc in its current location when minimum runout reaches less than 0.05 mm (0.0020 inch); otherwise change the disc and conduct further runout measurements. The last step involves placing the torque plate and the 2 mounting bolts; apply torque using settings of 88 Nm (900 kgf-cm, 65 ft. lbs.). The item reassembly sequence starts from disc brake grease application to specified components while following an inverted schedule to disc disassembly.
