Hello. We will be happy to assist you. The brake pedal being lost is likely related to a hydraulic leak and the brake pedal being hard might be related to a faulty brake booster. When changing the ABS pump the brake system will have to be bled to get the air out of the system otherwise there will be a low or spongy brake pedal. A brake pedal being hard is a sign of a faulty vacuum brake booster. The brake booster should take vacuum from the engine and create additional stopping power to apply when you the driver presses the brake pedal. If the brake booster is malfunctioning the brake pedal will be hard to push because your braking system needs a vacuum force to create additional stopping power. It may be a hose to the vacuum booster causing an issue not the vacuum booster itself. I suggest to have a technician perform a brake evaluation on your vehicle.

How to Identify and Fix Common car Problems ?

Options you should be sure to get are the anti-lock brakes with electronic brake-force distribution ($300) and side-impact airbags ($250), both of which can save lives and reduce injuries in an accident. Other options include cruise control ($250) and a sunroof ($750).
The anti-lock braking (ABS) system is used to maintain wheel motion and traction while braking, accelerating or cornering on a slippery surface. This system uses the same components as the traction control system (TCS), and the functionalities of both are integrated through the ABS control module.
When your ABS system malfunctions are can also cause a spongy brake pedal. Your ABS system is designed to allow the driver to maintain more control of the car in a high-speed stop.
One reason your vehicle`s ABS light is on is that it may be sensing abnormally low levels of brake fluid. If your brake fluid is low, you will be able to notice through the quality of your car`s braking as it may seem soft or spongy. In some cases, you may need your car`s brake fluid replaced altogether.
This is in addition to optional anti-lock brakes with electronic brake-force distribution, which improve steering control in an emergency stopping situation and enhance braking stability and effectiveness. Cloth or leather, the seats are comfortable and supportive.
Only the LE carries the option of leather, but alloy wheels are available on both S and LE models, along with a tilt and slide sunroof. Unfortunately, cruise control, ABS, and side-impact airbags are only to be had as options on all Corollas. We`d like ABS, at least, to be standard fare.
The four major components of ABS are speed sensors, valves, pump, and electronic control unit (ECU).
If the brakes are soft or spongy, this is a good time to change or flush the brake fluid. Flushing the brake fluid, commonly called bleeding the brakes, gets rid of the air. (Bleeding the brakes uses fluid to push air out of the brake system.) Over time, brake fluid absorbs moisture.
No. If your brake pedal feels spongy, your vehicle is not safe to drive. Identify and repair the underlying issue as quickly as possible. Spongy brakes are common and dangerous problems for any vehicle and indicative of a deeper problem.
The most common ABS problems occur when sensors become contaminated with debris or metal shavings. Malfunctions also occur when sensor wiring becomes damaged, resulting in intermittent or no continuity.
They pretty much the same thing except for a few sensors that the 2005 upwards have. The 2005 has key sensor factory security, Also has some sensors on the wheels, grill and reverse lights are different. Almost every other thing is the same. Go for the 2005, it`s more secure.
The CE, LE and Sport Corollas use disc brakes in the front and drums in the back, while the XRS gets discs at all corners. ABS and electronic brake distribution are not available at all on the CE trim, but are standard on LE and XRS. ABS is optional on the Sport.
Additional standard equipment includes anti-lock brakes with tire-pressure monitors, front and rear disc brakes, and cruise control.
If you see the light that says ABS, it means the ABS braking system might be malfunctioning. The antilock feature, along with stability control and traction control features, may be disabled.
All come standard with a five-speed manual gearbox. A three-speed automatic is a $415 option for the CE; a four-speed automatic is an $815 option for S and CE. Side-impact airbags are options for all three versions, but you have to step up to either the S or LE to get antilock brakes.
If your car is older than that, the easiest way to find out if your car has ABS brakes is to find a quiet road and relive your learner driver days by performing an emergency stop – if your car has ABS it`ll stop without locking its wheel, if there`s no ABS your wheels will lock and you`ll slide to a halt in a cloud of …
ABS technology significantly lowers the risk of your wheels locking up and your vehicle skidding, especially in slippery conditions. It is no exaggeration to say that this can be life-saving, helping drivers to maintain control and to steer out of potentially dangerous scenarios.
ABS sensors are classified in to two different types, Passive and Active. Passive is without a power supply and Active is with a power supply. These comprise of a wire coil wound around a magnetic core and a permanent magnet.
There are four main components of ABS: wheel speed sensors, valves, a pump, and a controller.
These include disc brakes, drum brakes, and the parking brake. Disc brakes and drum brakes perform the same task of slowing your vehicle when the brake pedal is pressed but use different parts to do so.
In an anti-lock braking system, your car`s wheel speed is monitored and if wheel lock is detected, a sensor sends a message to a controller that releases and applies the brake up to 20 times per second, preventing a lock up and helping you maintain control of your vehicle.
1) Line pressure can only be increased by either increasing the mechanical pedal ratio or by decreasing the master cylinder diameter. In either case the pedal travel will be increased. 2) Clamping force can only be increased either by increasing the line pressure or by increasing the diameter of the caliper piston(s).
Pedal and hold Hold. Bleed. Repeat. Loud callouts of “pump it up” or “pressure” and “hold it down” can make the garage or driveway sound like a Sunday morning at the Waffle House, but the two-person procedure is a tried and true way to get the brakes bled quickly.
As stated prior, if the rotors weren`t machined or lightly surfaced when the pads were changed, that will give you a spongy feel as you are not stopping as effectively and takes more effort to slow down. With new rotors and pads, the machine marks on the rotors help to break in the rotors and pads together.
