Soft brake pedal on a long descent
You are driving a loaded manual estate car down the Jordan Valley road toward the Dead Sea. The descent is about 8 km long at 6–8%, the speed limit is 80 km/h, and you are in fourth gear at 70 km/h. After about 3 km of repeated braking for bends, the brake pedal feels soft and travels almost to the floor before the car slows. You can smell hot brakes, the brake warning lamp is not on, and the handbrake is a conventional lever. There is a truck 60 m ahead and a car 25 m behind. The next safe pull-off is 400 m ahead. Your passenger is anxious. The road is dry and it is daylight.
1. What is happening and what are your immediate actions?
Read the worked answer
The pedal going soft and long after repeated braking on a long descent points to brake fade, possibly with overheated fluid or a leak. The immediate aim is to slow without relying on the brakes.
- Release the brake pedal, keep the car straight, and change down to third, then second, using engine braking. Do not coast in neutral.
- Switch on hazard lights. Pump the brake pedal gently to see if pressure returns; if the pedal still goes to the floor, do not keep pumping hard.
- Use the handbrake progressively, not as an on/off switch, to avoid locking the rear wheels.
- Aim for the pull-off 400 m ahead; keep the engine running so power steering and brake assist remain.
- Do not turn off the ignition or engage park while moving.
2. How do you stop safely at the pull-off with a truck ahead and a car behind?
Read the worked answer
With a truck ahead and a car 25 m behind, I need to slow early and predictably.
- Lift off, downshift, and use hazard lights; brake gently with what pressure remains, and use the handbrake in small increments.
- Signal right to leave the road, because traffic in Jordan keeps to the right. Check the mirror; the car behind may not expect a stop. If it is too close, I still slow gradually rather than brake suddenly.
- Stop on the shoulder, away from the truck's path, apply the handbrake, select first or reverse, and switch off only after stopping.
- Put out a warning triangle if it is safe and required, and keep passengers away from the traffic side. The key is a controlled stop; a sudden stop could cause a rear-end collision.
3. What mechanical checks or decisions should you make after stopping?
Read the worked answer
After stopping I would treat the car as unroadworthy until checked.
- Look for brake fluid under the wheels and check the reservoir level; low fluid suggests a leak. Do not open a hot reservoir cap.
- Check wheel temperatures by looking, not touching; a much hotter wheel may indicate a dragging brake. A soft pedal that recovers when cool still needs inspection.
- I would not continue the descent. I would call for recovery or a mechanic, tell the examiner, and arrange another test. Brake fade can return on the next bend, and the risk is not worth the appointment.
