I'm new to this forum so please bear with me.
A couple of weeks ago my pump stopped working and brakes went really spongy, I gave the abs relay a shuffle and the pump turned on for a second and then switched off. I took the relay out and it rattles, so I've replaced that with a new one. (Pump still doesn't fire up) Abs and traction control lights are on and breaks seem to be working still with a few pumps. I've tested all appropriate fuses for power and power is going through them and to the relay. When I attached electrical tester to wires that go to the switch, my pump turned on. Just today my brakes now completely lock up when I reverse with my foot on the brake and have to use the handbrake when reversing and not touch the brake pedal. Any help or advice would be very appreciated as im stumped as to what is going on. Thankyou
