1992 Suzuki sidekick has front brakes locking up after a short drive. Problem started after right front caliper piston was frozen and left front caliper slides were frozen. Replaced right front caliper and...
stop and do not drive, get a brake man, in the loop, danger !
this is cause by the MC, the master cylinder, no ABS in 92
not replacing relic calipers in pairs is dumb, sorry risking life and limb using old 20 year old calipers is not bright. a fact, not opinion.
are both caliper locking, at ONCE?
that is the key question .
reasons. (answer for BOTH clipers locking at once)
1: bad calipers ,no piston lasts for 21 years, ever. (relic)
2: the MC piston is not retraced,
#2 is caused for 2 or 3 reasons,,,,
2a; brake pedal adjusted such that the factory play behind piston rod is not zero or minus, causing the MC to lock hydraulically.
2b; the booster was changed and the PP mechanic (weak) did not
RTM , they did not adjust the new booster, calibration ring stated in the FSM.
3: if one caliper (good) locks the rubber flex line is breaking down
inside and is clogged. 21 year old lines are not good to trust.
not life and limb or mine when you hit me...
that too, is fact.
the guide pins must be free, and antisieze lubed or with special
99cent OTC brake grease (very high temp rated,) ask.
the pistons rust. DOT3/4 is hygroscopic and will rust in 21 years.
not a guess. fact.
One other point, 21 year old caliper seals will no longer have
stiction, they fail to retract the piston and the pad drag. wasting fuel and pads. new seals. better, newly rebuilt Raybestos calipers
will make them safe.
fixing brakes in a serial fashion is asking for trouble.
do not cheap out on brakes.
