Hey all,

 

Decided to replace rear discs/pads but fell at the 1st hurdle.

Seems like the upper cradle bolt is rounded aarrgghh..So looks like a garage job, feeling the blot will need to be taken off with forceful tool.

 

Anyone know what bolts these are and best place to get 4 new ones?

 

Cheers 

Skoda will probably supply them still.

 

What size are they? An imperial socket might be able to be tapped on to it with a tickling stick. Or I have even used a whitworth socket on a metric bolt.

Item 13, part number N90740302 ?

Mine were the same. Removed them with a set of stilsons.

Was that the 10inch stilsons? 

A-ha! Don't need to lose the carriers to change the rear disks. If the problem bolt is the carrier/caliper pin/bolt. (With the thin head), Get something on it any way you can and it'll come out. There is a thread lock compound on it and the pin has flats to hold it from rotating.

 

It was the calliper to axle hub he was talking about.  It has been many years since I replaced rear discs on a similar Polo, but to make life easier(?) I also took off these bolts and replaced them with new ones after fitting new discs - I had done this job a year before on my 2000 Passat so I just prepared for that job on the 2002 Polo in the same way. Now, I looked up the description of these bolts on the link Wino provided and it sounds very much like these bolt head are round and they have a recess in them which is hex - so, is that the problem, cleaning out that recess and tapping in firmly a hex key bit has always worked for me when faced with that type of bolt head.

 

I seem to be very generous with Loctite on the calliper guide bolts, that means more work when I get the bolts out!

 

Edit:- on reading the opening posting maybe I'm wrong and it is the hex recess that is now round off - oh bother!!  Is that when you try to trash some suitable Torx etc bits?

12 or 15 inch, little at a time and slow due to access. Then mole grips when freer.

Yes it's the round bolts with the hex recess. The torx bit fits fine in the bottom bolt but the top bolt it just doesn't catch (hence the rounded statement).

 

I did think about persuading a large bit in and may try that. The bolts are welded in place! Wondered if they've ever been out lol
