M.O.T Failier Brakes

[robdog]

  Went for the dreaded MOT today and apart from a few dodgy light connections they pulled me on worn brake discs. Shot down to spares shop and picked up new discs and pads, off with the wheels only to find the two bolts holding the caliper in place absolutely mullered and not budging. Gave it some heat and penetrating oil but no joy. Is there any way to get disc out without removing calipers? Otherwise it looks like the whole swivel pin housing will need to come off to allow for bolts to be cut holes drilled and tapped and new bolts put back. Anyone have any other ideas. :'(

Can't really help sorry ....

them bolts are in an awful place too... :(

there are sockets that grip the flats of the bolt rather than the corners could be worth a go getting one the right size from a good tool shop...

You need to use a hexagonal socket, the 6-sided ones give you a good fit, if the bolt wont play then try a slightly smaller size and and tap it onto the bolt, then pray

good luck

The bolt heads are badly rounded can get 13 ring spanner on but not the 13 socket, have tried a bit of gentle persuasion with a lump hammer but the socket just wont go and a 14 goes on but there is to much play so it will only make the situation worse I fear. Might have no option but to give it to a garage and ask them to do it in the week so that I can get a retest within the 10 days.

i think what you need is a torx socket not sure of size

go to landrover buy new bolts ( which you need anyway) then go halfrauds

hth  ;)

No not a torx, a normal socket but needs to be a six point socket as said earlier rather than 12 point. As I found out a few months ago the six point ones are difficult to find these days.

I am trying to remember what the hub area looks like? as I'm stuck in the house and havn't seen the Landy for a few weeks now!

Can you disconnect the brake pipes and steering arms then remove the whold hub? Get to it that way?

[robdog]

 :D Well a new day and a new approach and its sorted. The bolts were not torx but they were 12 sided so got some sockets from halfords a no 13 is needed, managed to get the bottom bolt off after applying a lot of heat then took out pads and tapped the calliper up and down and that loosened the top bolt. I gave it loads of heat and took a 12mm socket and hammered that on and it came lose. have ordered new bolts all round. The bolts that hold the disc onto the hub were also 12 sided bolts size 14mm. I found that if you lay the wheel flat on the ground and lay the disc and hub back in the stud holes of wheel it makes loosening the disc bolts easy as the wheel holds the hub and stops it trying to turn when loosening the bolts.

Thanks to all for your suggestions

Glad you got it sorted.

[Andy41]

glad you fixed it, had a look this afternoon and your right they aint torx just 12 sided. :)

Make sure you put a locking compound on the new bolts, they will come loose if you do not no matter how tight you do them up. Old bolts, its the look of the draw, some do some don't.

[robdog]

Oh yes Lock tight on all bolts is a must, not only does it keep them in but also stops them from corroding and becoming one solid unit with the item they are bolted to.
