I've noticed that when the brake is engaged, the left wheel brake doesn't completely lock the wheel in place. In fact, it's quite easy to move it. Is there something I can tighten or replace to fix this?
You can adjust the tension in the brake cable, there are instructions in the manual. Also check that you have the brake handle in it's furthest position. It can be quite stiff and takes a bit of force (especially if new) but it may go one click more than you currently have it.

If a button latch fails to engage, it often is due to a weak spring. Some wiggling action may get it to pop out; otherwise the part inside the handle will have to be accessed which could prove to be virtually impossible.
Inspect the stroller's wheels and handle to identify the type of brake mechanism it has. If the device is equipped with wheel-mounted brake levers and swivel locks, use the toe of your shoe to activate these mechanisms. If your stroller is equipped with a handle-mounted brake lever, push down on the lever to engage the brakes. Some models also come equipped with a secondary-locking mechanism located on one of the rear crossbars; use the toe of your shoe to activate this feature. Step 2
Lift the handle or press the tab securing the backrest in place, located on the upper edge of the backrest or on the crossbars securing the rear of the backrest to the frame. Grip the edges of the footrest, then lower the component by pushing it into the desired position. Pull back the stroller's canopy. Step 3
Grip the stroller's handle and lift the device upward; if the stroller comes equipped with a safety button, press the button as you lift. Use the toe of your shoe to push on the stroller's hinges until the frame begins to fold. Step 4
Pull the halves of the stroller's frame together until you have completely folded the device; if the stroller comes equipped with a locking latch, engage the latch to keep the halves from sliding apart.
A bugaboo brake fault can be caused by any one of the three parts that make up the brake system.
1/ The cable and cable adjustment screw. 2/ The brake lever assembly. 3/ The brake shoe assembly.
I've listed the three parts in the order of most likely to cause your brake problem. First I'll give a quick over view of how the brake should work then we'll look at the 3 parts in more detail.
Lifting the brake lever up pulls up on the brake cable, a ratchet in the lever keeps any tension until you press the release button in the centre of the lever. The cable pulls up on a toothed brake shoe and via a connecting axle a matching brake shoe on the other side, these brake shoes engage a set of matching teeth on the inside rims of the rear wheels thus locking the wheels.A spring on the cable side brake shoe disengages the brake shoes when the release button disengages the ratchet in the brake lever.This is a simple system with most parts in plain view so you can see the operation of all parts except the ratchet inside the lever.
1/ The brake cable is the most likely cause of most brake problems.Like all cables they can stretch, stick and snap.If the brake lever seems to work OK but the breaks don't hold very well try adjusting the cable tension by winding out the cable adjustment screw at the bottom of the cable thus taking up any slack and bringing the brake shoes up tighter into the wheel rims.A sticky or broken cable should be obvious by observing the brake action as you pull and release the brake lever.Run some sewing machine or 3 in 1 oil down the inner cable wire if it's sticky. If broken you can make anew cable yourself. You will need a universal bicycle brake cable kit and a solder less nipple. The Bugaboo has an odd double nipple design. Your replacement cable will only have one end the same as the Bugaboo.The other end will be either bare or have the pear style nipple.This you would cut off.Using the old cable as your guide, you cut the new outer cable to 75 cm and fit the ferrules supplied with the kit. The matching nipple will be the top (lever) end of the cable, reuse the old adjuster and slip it on to the bottom end followed by the solder less nipple.Set the nipple 89 cm from its opposite.Depending on the cable and nipple you buy you may need to drill the plastic parts out to ease the fit.If this sounds to complicated just print this out and give it to your local bike shop.
2/ The brake lever assembly is made up of the lever, a release button, a small compression spring and the outer bracket that holds it all on the handle. The bracket also holds the left handle release button.The most common problem is the ratchet fails to hold and this is a safety issue as it can fail quite suddenly!Either the small compression spring has broken (unlikely) the screws holding the assembly loosen (hopefully) or the teeth on the button and outer bracket have worn down (most likely).Try first to tighten the two screws, if that does not help take the two screws out.It's a simple mechanism the button sits inside the lever it can move in and out of the lever but can't turn as it has splines that lock it to the lever.A compression spring pushes the top outer edge of the button against the inner side of the bracket; they both have serrated teeth that lock them together. The raised centre of the button protrudes though the bracket.Pushing on the center of the button disengages the interlocking teeth of the ratchet. The compression spring can be found in most hardware stores, worn ratchet teeth can be reshaped with a rotary modeling tool like the Demel.
3/ If the Brake shoes are the problem it will be obvious,broken expansion springs are easily replaced, stripped threads on the cable adjuster can be sorted at your local bike shop and broken parts either repaired by a plastic welder / bumper repair shop or replaced with parts from a salvaged frame. The most common problem is one shoe engaging before the other. Take the screw out of the connecting shaft of the shoe that engages first adjust shoe to match other side and drill a new screw hole.
I did not have to disassemble at all. Thanks to your comments. I just took off the wheel with the stuck pin; gripped the pin with large pliers and a tight grip; pulled slightly outward while turning pin. Did this a couple times and the pin shot back into place!
When folding the Vibe some important things to remember are that the handlebar must be in the most upright position (perpendicular to the ground), nothing can be below the rear axle level (ie. lift the basket up above this) and the front single wheel should have the side with the attachment bar on the outside.
The fold locks will not engage if everything is not in the correct position. If everything is in the correct position the fold locks will easily engage/disengage. If everything is NOT in the correct position the fold locks will not engage and should not be forced.
Put handle bar in upright position.
Undo the side lock clips. Then you lift the red lever on the side to start the fold. Fold so that the pram front wheel and handle come together.
As the pram folds ensure basket is above rear axle and the front wheel has the attachment bar on the outside.
When the pram is fully folded you can fold the side lock clips back in place.
you need to make sure both seats are upright, the storage basket bar is up and locked in place, the canopies are pulles back and out of the way, and when you lower the stroller to fold it shut, make sure the wheels are not sideways and in the way. the front wheels need to be straight, if they are crooked the stroller will not shut completely. if you still need help i'm at firstname.lastname@example.org
I have just fixed my stroller which had a similar problem. The wheel was still swivelling but it was sticking slightly. I noticed that the pin that locks the wheel in place was half out and therefore the wheel was getting caught on it. I undid the nut that holds the end of the wheel lock cable in place and tightened this as tight as I could which pulls the pin back into place (making sure that the switch is in swivel position). I then put the washer and nut back on (making sure cable was as tight as possible).
the brake disengages using the button. if it is forced the mechanism slips. its fairly straightforward to take it apart with a screwdriver. clean the plastic parts, put it back together right and screw it back on. then all you need to do is show granny how to work it (again) to prevent it happening again.
