answer : It indisputable sounds as if the right front brake caliper piston failed to properly draw in or bind of the caliper ‘s slide pins caused continuing clamp of the bracken pads. A faulty wheel bearing can generate considerable inflame besides, but would have extra identifiable symptoms such as relax and/or noise. estimable job identifying the excessive heat was localized to one wheel, as that rules out a battalion of other possibilities ! Your Town and Country van employs disk brakes on the front axle. Single piston calipers squeeze brake pads against the bracken rotors as hydraulic pressure is applied by the master cylinder. When pressure is released, a square cut seal surrounding the caliper piston twists bet on to its relax status, drawing the piston always so slightly rearward. This natural process, along with a slender amount of knockback from rotor run-out, allows required brake pad/rotor headroom. The brake caliper floats on pins, allowing the caliper ‘s single-side clamping effect to be equalized to both sides of the rotor and loosen to an drop side.
Your remark about the brakes being recently renewed means the caliper pistons now reside profoundly within the caliper give birth, in an area previously exposed to possible corrosion and sludge. Brake fluid attracts moisture, and without periodic refilling it ‘s possible to encounter problems such as pit of the caliper yield and or gluey antilock brake solenoid valves. Contaminated bracken fluid is besides a possible perpetrator. Should a petroleum based fluid be incidentally added to the fluid reservoir, swelling rubber seals can lead to a variety of problems. I wonder besides if the caliper climb pins and bores were cleaned and lubricated at the time of brake service. If not, it ‘s possible for them to bind. There ‘s a reasonable find this could occur again. After double checking freedom of caliper drift, I ‘d consider renewing both front calipers, just to play it condom.
