Brake system
« on: May 27, 2015, 02:35:39 PM »
Can anyone help please, ive done nearly all the jobs for my mot retest, but I still have a pain the backside 1. The failure is the brakes ar spongy, ive replaced the rear pads and bled the system but still seems to be spongy, wondering if it could be the vacuum unit and if so are they easy to change or is it a garage job.
just to give an idea of what the man bloke said I quote Brake pedal creeps with the vacuum fully depleted, ive checked the levels and their fine. so any help please would be greatly appreciated. Ive checked the forum but cant find anything that covers this problem.

I would interpret that as the pedal is sinking to the floor slowly when keeping pressure on the pedal, this is usually fault with master cylinder seals.

Are there any diagrams of how to change the master brake cylinder please. as I think that's the problem so I can cure 3 things in one go. Thank you, mines a 02 plate no abs fitted.

Are you sure it doesn't have ABS? I thought ABS was a standard feature on all Mk2 Galaxies! I don't think there's any procedure covering master cylinder removal and refitting here, at a minimum you'll need to remove the airbox & plastic pipe that connects the MAF sensor to the metal air pipe that feeds into the turbo (assuming it's a TDI!), and the plastic scuttle at the rear of the engine compartment, in order to open up some access to do the job. Then it's just a case of removing the brake pipe unions from the cylinder itself and unbolting the unit from the servo, all whilst trying not to let too much brake fluid leak out! Thorough bleeding after replacing the unit is essential.

Before doing this, have you checked to ensure there's no other visible leaks from the brake lines, calipers etc? It should have been picked up on MOT if there was anything obvious but just sayin'.

The master cylinder is pretty straight forward to replace, you will need to remove the bulkhead scuttle tray and air filter box to give better access after that undoing the brake pies from the cylinder and the two nuts securing the cylinder to the servo

yours may look slightly different with more pipes attached.

Can you check and amend your vehicle details if it's year is 1998 it's a MK1 also your engine code is useful
