Loss of brake pedal: This condition is usually a result of brake fluid leakage due to failure of a brake hose or a rusted metal brake line, a worn wheel cylinder or brake caliper, or a worn master cylinder. A simple once over of the system will reveal what's going on.
If you have questions about a specific purchase, it would be best to speak to an attorney who could inform you of your legal options. While there are laws that allow for a 3-day right to cancel certain purchases, these laws are very specific and do not apply in a majority of consumer purchases.
If the car dealer exercises its right to cancel the purchase contract within 10 days, you are not required to sign a second contract to purchase that same car. Let me repeat this. A car dealer cannot force you to sign a second contract. If the car dealer cancels the purchase contract with 10 days, you are obligated to return the car, and the car dealer must give you back any down payment or trade-in that you gave with the purchase. The car dealer cannot cancel the purchase contract after the 10-day period has expired. If a car dealer tries to do this, you should advise it that your understanding is that the car dealer is no longer entitled to cancel the purchase contract, and ask the car dealer to send you a letter explaining why it thinks it can still cancel the purchase contract.
