Hi Alanmarshall,

I guess the rear brakes system of your bike must be mechanical.
Remove the rear adjusting nut on the brake rod and thn try it , the wheel should rotate freely.
If no, thn theres a problem in the drum and the linnings.. you will hve to remove the back wheel and examine.
If after removing the adjusting nut at the rear rod it moves freely thn theres a problem frm the rod to the brake pedal.
Or it may have been tht the adjustment was too tight without a free play .

Hope this helps!

    Hi Alan,



    Ok, all you have to do is loosen the bleeder neeple at the caliper and some brake fluid will pour out , this should release it.

    You may have to overhaul the caliper probabely the pisston has rust on it and thus the sticking.

    please visit this site for more information.

My brakes keep locking up on 2001 ford taurus what causing it?


Could be sticking disc brake caliper(s), or sticking rear wheel cylinder(s). If one wheel locks up before the others, that would likely be the problem caliper or cylinder, since that brake wouldn't fully disengage, and would therefore be dragging (which would accelerate the wear on those brake pads or shoes, also).

Brakelight stays on


You need to identify which brake light switch is sticking, simply unplug one switch at a time to determine the problem. It is possible that a brake light wire is chaffed and causing a problem but the most likely suspect is are the brake light switches. You can use a volt ohm meter to see if the switch circuits open and close when the brakes are applied.

Ave developed a loud humming type sound from the rear wheels of a 2007 Tucson. It seems to happen after driving several miles and is constant except when I touch the brake pedal when it momentarily stops....


Rust can build up in the rear calipers between the bracket and pad. This causes the outside pad to stick. When 15,30,45,60k etc services are done at a dealership, cleaning the rear brakes is a normal part of the service.

My mountain bike has a disc brake problem......... when I sqeeze my front disc brake,it locks my front wheel... though I stop the brake ,it still locks the wheel temporarily........ ...


3 possible issues:

1) the cable is not moving through the housing freely. There could be a burr, a bend, a worn end or just simply rust in the housing and that is binding the cable up, not allowing for the return spring to happen and essentailly stick closed. Rock and Roll cable magic lube is the a great solution for the sticking cable. If it is bent or the end is worn then you need to replace.

2) The springs on the actual brake are binding. There should be an adjustment knob on the brakes to adjust the tension. If this does not work, then check the cable binding again.

3) The pads and/ or springs have some sort of problem. You can remove the pads and springs, clean and replace and see if the pads themselves are just sticking.

If none of these solutions work then you will need to go into a bike shop and have the mechanic look at it. You may have a broken part somewhere in the brake or lever or both.

Good luck, my guess is it is just sticking and cleaning the pads and lubing the cable will get it to stop sticking. By the way any bicycle lube will work down the cable, the Rock and Roll is just a special cable lube for sticky situations.

Cylinder head torque spec


I am not that familiar with the Yamaha but this is what I could find in my research, I also asked my husband who is a bit more familiar and he said either call the shop and see if they will provide the info or purchase a manual at the shop or online for your bike. I am providing you with the info that I found and I hope that it will help you in your endeavor as I know it can be very difficult to locate some info that you desperately need sometimes.. Thanks in advance and I hope it helps. See below. Stormi

Cylinder;The cylinder shaped space (obviously) in an engine where the piston moves up and down to compress and explode fuel, which generates the engine's power.

TORQUE:The tendency of a force to cause an object to rotate. In an engine, the torque is expressed as the force applied multiplied by the distance from the center of rotation. It is the basic measure of the propulsive effect of a powered wheel. Or, said in other words: The measure of the force applied to produce rotational motion usually measured in foot-pounds or Nm. Torque is determined by multiplying the applied force by the distance from the pivot point to the point where the force is applied.


Max Torque
5.5 kg-m @ 7500 rpm

The Yamaha XJ650, also called the Maxim 650, was part of the Yamaha XJ series of high-performance, cruiser-class motorcycles. Yamaha manufactured the classic-style street bike from 1980 to 1983. The Maxim's design and horsepower-to-weight ratio made it a precursor to the modern sport bike.

Engine
1. The 1981 Yamaha XJ650 Maxim was powered by an in-line 653 cc, four-cylinder, dual overhead cam engine with eight valves. The air-cooled, four-stroke motor used four 32 mm Hitachi carburetors. Its bore and stroke measured 2.5 inches by 2.1 inches with a compression ratio of 9.2:1.
Chassis
2. The Cardan shaft-driven Yamaha Maxim had a five-speed gearbox. The air-assisted 1-inch (26 mm) front forks had 5.8 inches (147 mm) of wheel travel. The five-way adjustable spring preload rear suspension had 3.8 inches (97 mm) of travel. The bike had a hydraulic single-piston, single-disc front brake with an expandable drum rear brake. The Yamaha XJ650 had a curb weight of 509.3 lbs with a seat height of 30.7 inches.
Performance
3. The Yamaha Maxim generated 71 horsepower at 9,400 rpm with 39.8 foot-pounds (5.5 kg-m) of torque at 7,500 rpm. The bike's quarter-mile time was 12.6 seconds at 107 mph. Its top-end speed was 120 mph.
