highlandmist Posted December 1, 2012 Share Posted December 1, 2012 Remember the song by The Sisters Of Mercy, well this is nothing to do with them. I started on the brake disc / hub / caliper replacement job this morning. I was aware that I might have corrosion issues and I wasn't wrong. First of was the brake hose nut which I actually got moving, then noticed that the pipe was turning with it ! I moved onto the 13mm 12 point bolts on the calipers. Now the easy to get at one didn't look too bad, I could actually see the points and I did manage to free it up after some WD and wire brushing. I applied the same treatment to the other one although at first I couldn't make out any of the points i began to see them. I hammered the socket on anyway making sure it went on right. Alas I was unsuccessful. Feeling some movement and hoping for the best I checked the socket to see that it was just rounding the bolt head More brushing and WD then I hammered on again and got the same result. Wonder if its worth getting a wee blow torch to try heating. I have those "easy out" bolt removers but cant get in aboot because of the suspension spring. Put the wheel back on and went shooting. EDIT : Oh carp I forgot I had those Irwin gripper things, I've also got a 1/2 inch 12 pointer I can try !! Gave up too easy today will try again Wednesday. Need to get new brake pipe + fitting though I reckon. Quote Link to comment Share on other sites More sharing options...
Eightpot Posted December 1, 2012 Share Posted December 1, 2012 heat with a blow torch and squirt some Plusgas on - should release the brake pipe from the nut easily enough, caliper bolt will be a bit harder as the whole caliper will act as a heatsink, but plusgas works wonders.

dave88sw Posted December 1, 2012 Share Posted December 1, 2012 i always use 1/2 inch 12 point on those bolts to start with, its just a slightly tighter fit than 13mm, i've never had success with a 13mm. If not, use your irwins, those things are incredible. Quote Link to comment Share on other sites More sharing options...
highlandmist Posted December 2, 2012 Author Share Posted December 2, 2012 I've also ordered some brake pipe / fittings / flaring tool in case I make an arse of it. I will need to check out this plusgas stuff though. Quote Link to comment Share on other sites More sharing options...

Another vote for Plusgas and heat - I had a very seized drag link (you know what a swine these can be) that finally succumbed to this combination.

bushwhacker Posted December 11, 2012 Share Posted December 11, 2012 Hi WOW, that's bad looking, was it parked in the sea? It has to be rust how could anything got thumped into there surely the wheel covers most of the hub. Doesn't it? Good luck with the rest of it. I used to think I was the only one who come up against this type of problem but no we are not alone. Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted December 11, 2012 Share Posted December 11, 2012 ...... It has to be rust how could anything got thumped into there surely the wheel covers most of the hub. Doesn't it?...... If you look at the edge of the hole it's broken outwards so if it was a thump it was from inside of the disc bowl section. Maybe a bolt securing the disc came loose and jammed against the inside face cracking a lump out? Quote Link to comment Share on other sites More sharing options...
Simon Smith Posted December 11, 2012 Share Posted December 11, 2012 Seen similar before, I reckon someone did that trying to undo the disc bolts in the past and failing. So be prepared for them to be even more difficult than the caliper bolts. Quote Link to comment Share on other sites More sharing options...
highlandmist Posted December 13, 2012 Author Share Posted December 13, 2012 PlusGas is the one ! I have done the two front wheels now, hub bearings, discs, calipers and pads. Bleeding with a bleed kit tomorrow weather permitting. After applying the magic elixir I managed to remove every bolt with no drama. I also need to top up the swivel housing, both sides dropped some oil when I loosened the top bolts to remove the bracket. May see if local Autoshop has that oneshot stuff.

CwazyWabbit Posted December 13, 2012 Share Posted December 13, 2012 Bet your glad that's done Think I might be buying some plusgas having seen what you've managed to get undone with it! Quote Link to comment Share on other sites More sharing options...
cackshifter Posted December 13, 2012 Share Posted December 13, 2012 Yeah, Plusgas is The One. I went for the 5l can like this http://www.lawson-his.co.uk/eac-plus-gas-5-litre-dismantling-lubrican-p30703., and I fill a sprayer that originally held dettox or something like that. Seemed crazy at the time, but it's surprising how much you get through with Land Rovers, at least I certainly do, and it works out much cheaper.
