I have never been convinced that my brakes are working as well as they can be.

I have replaced the front pads and one of the front calipers. The system has also been fully bled through.

I have folowed the normal procedure if there is air in the system and tried pumping the peddle. The only affect this had was to make them worse and loose nearly all breaking power momenteraly. (Slightly scarey!)

Any ideas any one?

if the pedal went to the floor then there must still be air in the system or theres a leak somewhere,if the pedal is solid and very hard to press down with your foot then the brake vacume pump or servo is not working,

are the calipers actualy working? take the pads out and put a piece of wood in there place and gently press the pedal and see if the pistons move,don't do this without anything in the caliper or you may push the pistons out,try bleeding the system again starting with the caliper farthest away from the master cylinder,you could jack this wheel up over night as air will rise to the top of the caliper.

if all this fails you could always buy an anchor and thro it out when you want to stop

Could get very expensive in anchors!

Sound like it could be the servo or vacume pump then, any ideas how I can check that they are working?

Put your foot on the footbrake a few times to remove any vacuum with the engine off, and then switch on engine with the pedal depressed, as the engine starts there should be a give in the pedal as the vacuum rebuilds.

If not then dodgey Vacuum servo or pump.

Just tried the test, it does not repump very quickley.

Is there a way of testing the pump and the servo seperatly to see which is at fault?

Take hose off at the servo and put a finger across it. Should feel like a vacuum.
