V****a Rear pad replacment

[mattblack]

V****a needs some new rear pads. Interweb is giving conflicting info. re. retracting the pistons, some say you need a special tool to wind them back in, some say clamp the flexi, open the bleed nipple and push them back in.

 

Can someone give me the straight SP? It's a 2001 1.8 LS estate BTW.

If the handbrake works on the calliper, then yes, ideally you need the wind back tool, I have done some with pointed nose pliers before, but they are a pain in the arse to do that way, also be wary I'm not sure if the Vauxhall models have one calliper with a left hand threaded calliper like some of the other manufacturers do.

They just push back in.......either just let the fluid back to the master or clamp pie as you say. Handbrake has seperate shoes where the inside of the disc 'top hat' is a drum.

Cheers for that. Bit about clamping the line seemed to be to something to do with not pushing fluid back into the system and ballsing up the ABS?

[alf892]

Never heard of the ABS thing but clamping is quite a good idea because it get srid of the fluid in the caliper which is most likely to have absorbed water. Also avoids the possibility of 'disturbing' any slightly iffy master cyl components as can happen sometimes...

 

Only if nipple come undone though but you should be OK with this as caliper is cast iron.....just tap it on the end with hammer before attempting to undo

Is it these or Arstras where you flip the seals on the master cyl if you try to pedal bleed them?

Scrap it.

That would be the Mk3 Astra.. painful memories from years ago of working on a customer's car, coming flooding back!

Lacquer Peel- are you sure you're on the right forum?

You do not need any special tools to replace the rear pads on a Vectra B. The wind back tool is needed on MK4 Astras.

 

The handbrake is a separate drum and two shoe mechanism that is inside a specially shaped part of the disc. It's an utter twunt to adjust evenly on each side using the foutery wee adjuster cog inside the little drum and invisible unless you actually pull the sun in front of the inspection hole.

 

So no need to worry, just slide the old pads out and new ones in.

Watch for the spring clips rotting as you remove them though..... there are different fitting kits available, (same as Omega IIRC) it's down to disc thickness, which changes the lengths of the pins and clips. Best of luck.
