Question edited for clarity, full 'year make model' and no abbreviations please 'cyc' for 'cylinder, spelling 'braks, 'bleding'.
Question moved to model category.
It has ABS, you need a pressurized bleed system that puts the brake fluid in at the wheel slave cylinder end pushes it up to the master cylinder reservoir.
Or
You use a bi-directional Scan Tool Computer to open the ABS Valves.
The 1998 Sienna has one speed sensor in each tire (ABS sensors.) These sensors are used by the ABS system, but also to calculate the vehicle speed and for the tire air pressure monitor. If you are getting a P0500 code and your speedometer does not work, your problem could be a faulty speedometer. If one of the speed sensors were bad, the low tire air pressure light would come on.See http://www.fixya.com/cars/t21907247-transmission_speed_sensor
These seats are hard to get in and out, especially if the receiver hook on the floor has any obstruction; so first thing is to clear out anything that may be interfering with the seat from properly seating in the front hooks.
This fix applies to seats that are stuck and won't come out as well as seats that won't go back in.
Each seat has two levers on their back, marked; one for 'tumble' and the other for remove. Problem is, if you press the 'tumble' lever when the seat is out it may not let you replace the seat without first holding BOTH levers up while pushing the seat back into place, then pushing the seat DOWNWARD to reset the mechanism for tumble. Then, push the seat down so that the locking mechanism for tumble (a black lever under and on the drivers side of the seat).
If the receiver hooks are clear and the seat retainer mechanism is properly set you will be able to push the seat in and press down on the back of the seat and hear a very satisfying thunk that lets you know the seat is properly locked in.
These seats can handle quite a bit of shoving and jamming, and you may just have to work it hard to get them back into place.
I would unscrew the 3 screws and take the mirror out, to try and see why theyre not holding it properly. maybe use epoxy to fix the broken bracket and then screw the mirror back on.
Could be your shock absorbers , push down on both sides of the back wing , so push down and let go to see if both sides go up and down the same amount of times . Is one side more bouncy than the other Break light switch on the break peddle might need adjusting so check that , or use a multimeter on your back light good luck colin
low on fuel has two serious consequences
the fuel pump runs dry and destroys the plastic gears and
all the rubbish in the tank is sucked into the pump and filters and to the injectors
at this point , use a quality injector cleaner and see what happens as a misfiring injector is more likely blockage in the injector
