On a modern car, do you think a front brake pad could drop out of the carrier by itself?

You'd really need to elaborate more.
can a pad remove itself from its installation

someone i know had his brake pedal sink to the floor with loss of all braking...


i doubt his pad had left his vehicle if the caliper and carrier were intact

Some months ago I had the front Brake pads replaced on my 06 E7.....all ok.

I then at a later date had to take it to the garage because the back Brake shoes were binding, the hand Brake cable was also replaced.

As I drove out of the garage after having the Back Brakes sorted, I went to Brake and the pedal travelled about 30% further down than when I took it in. I phoned the garage back up explaining what had happened as it had taken me by surprise, their retort was to say that I should let them bed in and they will be alright.

A week or so later I had to return to the same garage re another car and mentioned that they still did not feel right, they said the same thing as before.

On Saturday night/Sunday morning I was doing a three point turn and noticed the Brake pedal almost went to the floor, but still managed to stop the cab [Just]. I pulled over and found that my Brake fluid reservoir was empty :shock:. I made my way to the nearest garage to purchase brake fluid and then put it into the reservoir but it made no difference. This meant it was not safe to drive so I made for home.

As I was driving for home I had to Brake, there was a clunk under the right hand side of the vehicle and my brakes failed totally - managing to slow down on gears and handbrake.

I feel that it stems from the Rear Brake job, remembering all the time that the Brake pedal from then on travelled further than when it went in.










Okay the mystery deepens!

I am trying to keep an open mind on this.

I get a phone call from the garage to tell me to come down ASAP, as he the mechanic had never seen anything like it in 40 years - leaving me wondering as to what nasties are in store.

The cab is up on the ramp with both the front wheels off, the mechanic guides my attention to the brake pads/calipers. He claims that when he took it all apart, all that was left on the brake pad issue was the inside pads on both front wheels - no outside pad on either wheel, absolutely nothing, no base,no metal..........nothing but an empty space.

As I said I am trying to keep an open mind........so!

There are no score marks or melting on the discs, there does not appear to be any burn marks through over heating of any kind. However I am wondering is it possible for both lots of outside pads to totally break up/disintegrate, bearing in mind I did hear a bang as the brakes completely went. We also discounted the fact that the pads on either were not fitted as the calipers so I am told would have scored the discs and most certainly made a noise of some descript.

My knowledge on cars is basic, to the level of doing my own service including in the past brake pads - on this matter I am fishing in the dark, which brings me back to can they just disintegrate.

Just to clear up any possible confusion caused by me; the drivers front outside pad missing, the inside pad intact. The passenger front outside pad missing, the inside intact.
