Where do you feel the vibration? if you feel it where you sit it is coming from back which is usually rear brakes. If you feel the vibration in your feet and hands it is coming from the front which could be your ABS or front brakes.

SOURCE: Left rear brake light stopped working but bulb and fuses are OK.

take the bulb back out have someone sit in car apply brake get your self a circuit tester and check to see if this circuit is carrying efficient 12 volt current! some times in cold weather these bulbs get hot with long period of breaking and when released condensate and rust begins and you get what you have perhaps bad socket! this would be a ideal location to begin and probably end,

SOURCE: Left turn signal stops flashing when brake pedal is depressed.

there is a ground problem, most likely in the tail unit itself, but a ground problem is hard to find and easy to fix. reground the system, the turning unit, and the problem should stop. About the hazards, I don't know...... some times in older cars, that is the way it works. because the brake and hazard element in the bulb is the same and the old cars used a break in the power, but the new cars use a break in the ground. any way, chase the ground down first, it is usually the cause.

SOURCE: brake pedal won't depress like it's frozen and brakes won't grab

Sounds like the pistons bound up in the calipers. Remove the calipers and attempt to seat the pistons in the calipers with a screw clamp. If no go, that's the problem. They can be replaced, but most folks just get a whole new caliper these days.

What is themaximum towing capacity of a 2010 toyota rav4 4 cyl?

depends on the engine capacity but 2.2ltr is 750 kgs un-braked (6x4 box trailer fully loaded) and 1000 kgs braked (10ft caravan)
remember that there is a regulation that you cannot tow more gross mass that what the vehicle weighs unless it is a brake controlled system ( electric brakes working of the foot brake)

My ed falcon has no spark an wont wind over unless ark the starter motor out?

Not sure what year or Country this question is for, Fairmonts have not be made in USA since the 70's.

If this is a late model car, there is a safety switch on the brake pedal lever or the clutch on a stick-shift that prevents the engine from cranking unless your foot is on the brake or on the clutch.

This switch often gets hit by the drivers feet and you lose the signal. Sometimes the brake lights won't work. So check under the dash and see if there is a switch on either pedal lever.

Bleeding the front brakes

Check the master cylinder as there are two pistons servicing to separate lines of brakes . When one circuit is bled the other piston will not work as the pressure before it holds it fully in . If there is a stop switch in the middle of the master cylinder you may have to remove it and blank of the hole to get it all to work.. The problem will be in the master cylinder

1988 Honda accord lx car on highway started shuddering and when braked it shut down, will start but unless you rev it shuts right down

88 is old car.....
is it a carb car or EFI car. this is a transition year, here in USA>
locations are never stated, here, so most answers are wrong.
this sounds like a sticking EGR.
the EGR opens at cruise and closes as you stop car
if it dont close the engine stalls. (or near)
its a 50,000 mile service item. we clean it.
in a shop the replace it, so it can go another 50k. but i clean mine.
so i dont have to pay $200.
there are vast numbers of reasons for stalled. but works out to just
4. (basics,) and the EGR.
if you get a tuneup, right, it will stop stalling

automatic trans , right?
may cars you just be in park and brake set hard. to start. (crank)
you meant will not crank, as no car (A/T) starts unless you first crank.
bad brake switch is the cause or is normal.
if curious as to rules. here.
the operators guide tells you this, on page, How to start engine)
if it dont. then see the FSM
or for how the park lock works.

Why would my brakes hiss when I step on them and cause the engine to rev up when I do this? It also makes the vehicle very hard to stop.

It sounds like your brake booster is leaking. The air hissing is the air going into the leak. This extra air goes into the engine and causes the engine to rev up. The booster is what makes it easy to push the brake, (when it is working correctly) which is why the pedal is hard to push.

Volkswagon bora 130 tdi is juddering with asr light coming on and staying on bit like changing gear at low revs but it does go not away unless turn car off and start again or turn asr off before driving...

asr works in conjunction with stop a wheel it(the car)thinks is loosing grip, from spinning.By applying the brakes to the wheel that is loosing grip,so the car is applying the brake. hence the juddering. if it stops when you turn it (asr)off it must be a sensor fault.easy way is to plug in the diagnostic computer to pinpoint faulty unit. if you dont drive very enthusiastically,then turn asr off until next mot/service.get back if you need any more info ....
