This problem has occurred five times in.
Abs brakes drop to floor intermittent.
Technically there are two main causes that would make the brake pedal sink all the way to the floor.
1 leak from brake line or brake caliper one of the reasons is the brake system loses pressure from an external brake fluid leak.
Certain component may also refference esp esc or use the traction control symbol.
No brake light or cel on the dash.
Pump brake pedal several times with engine off then push down brake pedal very slowly to see if it goes to the floor.
2001 ob 117 xxx miles.
When the abs system is not functioning then loss of traction skidding and hydroplaning are far more likely to occur under heavy braking conditions.
Either that or excessive amounts of air may exist within.
The sensors detect wheel speed and will send a message to the abs module to rapidly pump the brakes when it is detected that the vehicle is skidding or has lost traction.
There is a brake fluid reservoir which holds the fluid of the anti lock braking system.
By the way if you ever need.
Without any warning i lose my brakes.
I tried this and the pedal goes down lower than in test 1 but the pedal doesn t go completely to the floor.
The brake fluid has a lot to do with controlling the braking pressure within an anti lock braking system.
Sometimes there could be a leak from this reservoir which will cause the fluid levels to drop.
I have had the master cylinder replaced and the brakes flushed and replaced twice.
Pedal to the floor will not pump up.
This was of course an intermediate step towards.
Antilock brake system abs intermittent condition the electronic stability control esc may also be reffered to as electronic stability program esp depending on the vehicle model year and configuration.
Here s some brake service history that may also be relevant.
An excessively squishy brake pedal usually means that there s air in the brake lines and you may need to bleed your brake system or replace the brake fluid altogether.
If you hit the brakes hard like a sharp initial tap on the pedal they would work fine but if you eased onto them they went right to the floor.
