Hi
I have been searching through the brake threads to try and find an answer to my questions but need to check a coup!e of things.
I have a 3.0 TD 4runner and had replaced the front pads discs and calipers with new items bled the system as normal and no issues. The only thing it failed the mot on was hand brake efficiency and one of the pipes at the rear at lsv corroded. I found after taking drums off that the shoes needed replaced so I did that and cleaned the inside. I replaced both pipes on the rear axle and the one that goes from lsv to rear flexi.
Questions are how effective should the handbrake be, is it supposed to stop the vehicle if its in gear and you let it out on clutch pressure? It seems to be tight after adjustment but still moves when clutch is out only just though, there is resistance.
The other thing that is now happening is the brake pedal sinks towards the floor when you hold it with hard push when engine is running, I can't remember it doing that before...with engine off the pedal stays firm. I have bled the rear brake a few times now with no air coming out and it still seems the same. If I pump the pedal with the engine running the brake warning light flashes on. Reading posts this could be vacuum issue or master cylinder or is it something else that could be happening as this was fine after I replaced the front brake system and has only started since I did the rear, could it still be air?
