Front discs fail my MOT

[Krisis]

Hi All
I had my MOT on thursday and yes I knew about the welding but I failed on my front disc brakes

They are worn but on the brake test were perfect.

Anyway,
I wont be getting the replacements until monday and being the person that I am, old boy scout, be prepared and all of that. I would like to know if its as striaght forward as the it says in the books ? Or is there a nasty little suprise waiting for me?
I have ordered the following
1 x pair of discs
1 x pair of pads
1 x renewal kit ? (I was told to get this as it would be easier)

TTFN Kris (the krisis is nearly over! well this one anyway)

Don't forget the wheel bearings.
They are pressed into the discs so you might as well do the lot while you're there.

Do not buy cheap bearings though, go for go makes like timken, SKF, etc.

I haven't done one TBH but you've got the old can o worms surrounding removing brake lines corrosion snap scenario going on. Plus the disks house your front bearings best get new ones pressed into new disks rather than reusing old. Brickyard maybe best place to get bearings at the mo. I have a set greased and ready to go if your desparate but its a drive from Derbyshire.
Oh yes peening nut is supposed to be renewed pop the grease cap off and take a look how many times it has been peened. I think its a VW part only.

yes several nasties await the unprepared, get soaking all the nuts in penetrating oil 24hrs before you start undoing stuff esp the brake line connections.

.... also brake fluid and brake bleeding kit... the list goes on....

i haven't really looked at this job but i would have thought the brakelines can stay attached,,, it's the discs being changed not the calipers so the calipers can just stay on the flexi hoses surely?

[campervanman]

Yup, Calipers do not have to have the flexible brake hoses removed BUT to fit the new discs you have to unbolt the calipers from the hubs otherwise the discs cannot be slid onto the stub axle. There are two bolts holding on each caliper and they are torqued up tight. I cannot remember the size of socket you will need but when you have found out, get a good quality socket of the correct size and a long breaker bar otherwise they will never come off or, even worse, you will damage the bolt head

Look at the bearings before automatically replacing them, chances are that they have years left in them once re-packed.

The bearings CONNOT "be left in place"... they are fitted to the disc so have to be changed... (at least if it is a 2wd non south african model)

I strongly suggest you DONT use the GSF ones.. prob a good idea to speak with Brickworks as I am sure Si has sourced good quality ones..

[Krisis]

OK, I've done discs and brakes before but not on the wedge all I wanted to know is was there anything in particular that I needed to watch out for ie the big bar to crack and then to get the torque back up.

As it is I already have the replacement bearings, grease, brake fluid to replace the old and I even have replacement pipe if needed.

Possibly going to have fun with the caipers but will find out on Monday

This vehicle was owned by a right muppet who had bodged alot of things

Thanks All Kris

PS MOT guy said it was a tidy van ? but as I said it was owned and fitted by a muppet, did the job the easy way which is not always the right way

Contact Brickwork's re the bearings that is a must. If you take the calliper off remember there is a fixed piece of brake pipe on the end of the flexi, I broke that today and had to get a taxi to the motor factors to get another made up.

[toomanytoys]

There is no "BIG BAR" needed for the fronts.. if you do that the wheel wont turn.. Follow the procedure in the Haynes.. its good... you dont need to undo the big nut for the rear brakes either...

[Red Westie]

I think you mis-understood me....I was simply saying once the discs are removed the outters can be easily checked and a quick prag of the inner seals, quickly exposes the inners (two minutes a side)
You don't simply change for change sake, well not unless you have money to burn.
If I had automatically changed bearings everytime discs were replaced I would have had loads of complaints from customers quoting their consumer rights.
