How do I adjust the front brakes?

"Before riding the Stowabike for the first time you have to assemble the the handlebars, front wheel, pedals and the back rack. All the instructions how to exactly put everything together will be delivered with the Stowabike." See more assembly info in the link below, where the above text originated.

What's most important is the adjustment done once the bike is put together. For safety and proper operation the brakes and derailleurs (shift system) need to be properly adjusted, and sometimes the hub bearings as well. You may want to have a bike shop assemble it, or see if your community has a bike co-op, where you can use their tools and get help.

Firs, put a clamp (or a helper) to hold the working end of the brakes against the wheel rim, this will make the brake cable loose. Now loosen the "anchor bolt" (see three different kinds of brakes pictured below) where the cable attached, then pull the slack out of the cable and retighten the anchor bolt. That provides a big adjustment. Now to make a finer adjustment, use the adjusting barrel. Good luck!

The wound steel cable that connects your brake lever to the brake pads can be adjusted via a screw or nut at the top of the brake pad assembly. Simply loosen the assembly and gently tug the wire end toward the front of the bike tire to tighten brake grip; tug it backward to loosen. Tighten the screw partially to hold the cable in place, test the brakes with the brake lever, and adjust again if necessary before fully tightening. It may help to put the bike on a stand or hold it so that you can spin the wheel, check that the brakes are adjusted so that the pads do not rub the wheel. You can do the same thing with the rear brakes. You will need a small tool to loosen and tighten the brake pad assembly; your household toolbox should have something :)

While you are adjusting the brake tension you should also check the brake pads for signs of wear. If your bicycle brakes squeal, show uneven wear or are perfectly smooth, go to a shop and get a new set! Regular brake maintenance is very important for bike safety.

It ain't rocket science. Have the dealer put acid in the battery so it is ready to go into the frame pocket. It should come out of the crate with the rear wheel already mounted. The controls on the handlebars should already be mounted as well. Put the handlebars in position and bolt them in place. Put a box, or whatever you have, underneath the frame to get the front forks higher than the axle on the front wheel. Now put the front wheel assembly in place and insert the front axle. Add the washers and nut and tighten the nut. If the bike has headlights, remove the glass bulb assembly and hook up all the wires. Match the color coded wires; Black to black, blue/white to blue/white, green to green and so on. Mount the shift and rear brake levers if not already mounted. Ad fenders and turn signals and whatever else needs mounting. Install the battery, red wire to the positive battery terminal, black wire to the negative terminal. Now put some gas in the tank and turn on the gas petcock at the bottom of the gas tank. Note; some bikes do not have an actual valve for the gas. Turn the key on and watch for smoke from the wiring. If you hook the wires up wrong they can burn. If all is well, ( relax, all should be well ), go ahead and kick start the engine. Again, watch for anything odd. Now re-mount the headlight assembly and go for a test ride. Adjust the clutch and brake levers as needed. All done! You may want to ride over to the dealers and let them look at it just to be sure all looks okay.

With the tire not installed, push the brake calipers together and release the brake cable from one side, this should allow the calipers to spread fully. Now, install the wheel/tire into the calipers. Next, move the tire/wheel assembly around to get enough play to squeeze the calipers together and reinstall the cable in it's proper mounting location. Last, mount the wheel and tighten the axle.

If the following is not enough then maybe try Alldata.com which generally has more information, but it will cost: REMOVAL & INSTALLATION Chrysler Concorde, New Yorker, LHS Dodge Intrepid Eagle Vision

1. Remove the rear wheels and brake drums.
2. Remove the dust cap from the rear hub and bearing assembly.
3. Remove the cotter pin, nut retainer and wave washer. Discard the old cotter pin.
4. Remove the rear hub and bearing assembly retainer nut and washer. Remove the rear hub and bearing assembly from the spindle.
5. Remove the automatic adjuster spring from the adjuster lever.
6. Rotate the automatic adjuster starwheel enough so both shoes move out far enough to be free of the wheel cylinder boots.
7. Disconnect the parking brake cable from the actuating lever. Disconnect parking brake cable one side at a time.
8. Remove the both lower brake shoe to anchor springs.
9. Remove the 2 brake shoe hold-down springs from the brake shoes.
10. Remove the brake shoes, upper shoe-to-shoe return spring, automatic adjuster and automatic adjuster lever from the backing plate as an assembly.
11. Separate the brake shoes from the automatic adjuster mechanism.
12. Remove the brake shoe automatic adjuster lever from the leading brake shoe. To install:
    
13. Thoroughly clean and dry the backing plate. To prepare the backing plate, lubricate the bosses, anchor pin and parking brake actuating lever pivot surface lightly with lithium based grease.
14. Remove, clean and dry all parts still on the old shoes. Lubricate the starwheel shaft threads with anti-seize lubricant.
15. Assemble both brake shoes, the top shoe to shoe return spring, automatic adjuster and automatic adjuster lever before mounting on vehicle. Make sure the ends of the automatic adjusters are positioned above the extruded pins in the webbing of the brake shoes prior to installation.
16. Install the brake shoe assembly onto the brake support plate and install the hold-down springs.
17. Install the lower anchor springs and reconnect the parking brake cable to the park brake lever of the trailing brake shoe.
18. Rotate the serrated adjuster nut to remove the free-play from the adjuster assembly.
19. Install the automatic adjuster lever spring on the lead brake shoe assembly and the automatic adjuster lever.
20. Install the rear hub and bearing assembly. Install washer and retainer nut and torque to 124 ft. lbs. (168 Nm).
21. Install the wave washer, nut retainer and a new cotter pin onto the spindle. Install dust cap.
22. Adjust brake shoes so not to interfere with brake drum installation. Install the rear brake drum. NOTE: After installing the brake drums, pump the brake pedal several times to partially adjust the brake shoes. To verify proper operation of the self-adjusting parking brake, be sure that both rear brakes are not dragging when the parking brake pedal is released.
    
23. Install the rear wheels and lug nuts. Torque the lug nuts, in a star pattern sequence, to 95 ft. lbs. (129 Nm).
24. Road test the vehicle. The automatic adjusters will continue brake adjustment during the road test of the vehicle.

all new bikes come with assembly instructions
if there is no assembly book with the bike , don't buy it

There are adjustment screws just above the brake calipers where the cable ends . You can adjust the barrel screw that the cable passes thru. Turn the screw clockwise, which should allow more slack and allow the brake to lessen it's grip...
If that doesn't do the trick, you can loosen the clamping nut on the cable and let the caliper open up a little then retighten. take your time and be careful to make sure the brakes are working correctly before you ride..

It sounds like your self-adjusters are not assembled correctly allowing them to back off when braking.

1. the other end of the brake cable with the stopper,insert to the handle brakes.there is a guided slot for it.
2.go to the brake assembly.loosen the nut and find the small hole at the shaft of the flat head bolt.insert the cable.
3. adjust the brake.pull the cable until it is in the best tension,slowly rotate the brake nut to keep the cable in place.
4. try to grip the brakes and try pushing the bike while testing the tires if it skid.try to ride it to so that your weight will be calculated with the brakes.
5. adjust the brakes by repeating the above instruction until desired brake adjustment is achieved.
