How to move a motorcycle with seized brake calipers

THIS TIP GIVES YOU AN EASY WAY TO WHEEL A MOTORBIKE AROUND IF THE BRAKE CALIPER/S SEIZE & CHEAP SEIZED CALIPER FIXES

Most disc brakes seize due to corrosion, so the piston gets pumped out but cannot return on its own . Sometimes the piston seal gets dislodged with the same effect.

TEMPORARY CURE:-

With a rubber mallet or similar hit the brake calipers sharply on the out-most side where there are 1,2 or 3 round shapes in the cast metal, thereby forcing the brake pistons back a fraction.

BE VERY CAREFUL NOT TO HIT BLEED NIPPLES, BANJO BOLTS OR OTHER PROTRUSIONS AS THEY MAY BEND OR BREAK
If the calipers have opposing pistons ( the caliper looks similar on the inside) then you may have to do the same from the other side with a whack on a piece of wood or similar that passes through the wheel

DO NOT RIDE THE BIKE as the brakes will seize again as soon as they are used

For a permanent remedy completely refurbish or replace the calipers using new parts & fluid

After-market caliper rebuild kits are much cheaper than buying O.E. (original equipment) parts singly - as they are sold
Complete (original manufacturer) calipers for many modern KAWASAKI & SUZUKI bikes can be obtained (unbadged) for a fraction (<1/3) of the cost of O.E. calipers

2004 ele parking brake not pulling up to m.o.t s type jaguar


i presume you mean the electronic parking brake does not meet the minimum effort for mot test, first check the rear calipers and pads, the caliper sliders seize and/or the pads seize in the caliper frame, check the discs also for bad corrosion, is the park brake warning showing on the dash? if so check the wiring above the rear subframe its prone to chaffing and grounding out, the park brake motors are also troublesome, sounds like a pad/ caliper problem more than likely seized sliders easy job to free off, hope this is helpfull to you.

WHY DO BRAKES GRAB BUT MOT RELEASE ALL THE WAY ON 2004 NISSAN TITAN


Which wheel(s) are not releasing? Could be debris in the wheel cylinder(s) partially blocking the return fluid (drum brakes) or a defective wheel cylinder or cylinders or even defective calipers (disc brakes).

1988 Volvo 740 - renewed brake pads all around, new discs on front. Brake light is still on. Brakes seemed to seize for a short time, then released. Is this a problem with the ABS unit?, can I service this unit?

Brakes seize up and stay on after driving for a distance, especially in hot weather. They release when cooled down. Is this the master cylinder or calipers? Car is in good shape at 100 K. Garage kept all these years.


Jack car up, spin wheel, then apply brakes, and release and try spinning wheel again. If it doesn't spin just as easy, try cracking bleeder screw open, then try spinning wheel. If it spins easy after you crack bleeder screw, tighten bleeder back up & try same again. If same result, wheel spins when bleeder opened, then I'd replace the 2 front flex hoses that attach to calipers. If caliper doesn't release then you need to pull calipers and check if partially seized, or maybe slide pins that caliper moves on (that attach caliper to spindle) need cleaning and lube applied to allow calipers to move back & forth.
