Faulty break system

Recommended Posts

Hi,

My lexus GX 470 was having a break problem, suddenly the break stops working and the mechanic had to change the break pad and ever since then, the ABS, Vsc and a buzzing sound has been on, the break not still functioning, how can I resolve this?

It sounds like either there is air trapped in the ABS modulator block or it is faulty...either way, I would have it checked by a reputable garage to ensure nothing else is wrong with the system.

Also, if the pistons are forced back in without winding them back or releasing the bleed nipple to allow the pressure not to travel back up the system as this can cause problems with the ABS hydraulics.
