Ark Posted June 10, 2006 Share Posted June 10, 2006 Chaps, urgent advise needed please: I've got the car up on axle stands, wheels off, ready to change discs and pads. The problem is, I can't shift the buggers! The pins for the pads are _almost_ unmoveable...I shifted them about 4mm before realising that there's loads of meat left on the pads anyway, so no real need to change them, so I gave up. The discs do need doing, but I can't unbolt the calipers - loads of WD40 applied, and I'm attacking them with a torque wrench - the blasted thing's set for 150 lbs/ft and still the bolts are sticking - they're only supposed to be done up to 87 lbs/ft. So, has anyone got any bright ideas? Do I just go to Halfords and buy the longest breaker bar they've got? Thanks Quote Link to comment Share on other sites More sharing options...
Suprasteve Posted June 10, 2006 Share Posted June 10, 2006 re the pins, i had the same problem. Just lots and lots of WD40 maybe re apply over a few days. If that fails try and tap out using a pin that you'll successfully removed. If that fails start crying as you may need to saw in half and force out. re the bolts, again plenty of WD40 and lots of strength. good luck.

Ark Posted June 10, 2006 Author Share Posted June 10, 2006 OK cheers mate. I'm about to comandeer the wifes car to go to Halfords to buy a big fuck-off breaker bar too. Physics _can_ be your friend! Quote Link to comment Share on other sites More sharing options...
carl0s Posted June 10, 2006 Share Posted June 10, 2006 Torque Wrench is for tightening-up bolts BTW. You need a long breaker bar. I've had difficulty with my pins before, but managed to shift them. Then again recently, I had *major* difficulty. Ended up hacksawing through half, then grinding & drilling I put the new pins in with copper grease on them.

I'm glad that after inspection, I've still got plenty of meat on the pads, so I can shelf that job for another time. Still desparately need to replace my warped discs though...

Paul Posted June 10, 2006 Share Posted June 10, 2006 Pins, best way is to press them out if possible. Bolts - bloody big bar as already suggested. Paul Quote Link to comment Share on other sites More sharing options...
markymark Posted June 10, 2006 Share Posted June 10, 2006 If your changing your discs i would still change the pads as the old ones would have shaped themself to the old discs+ then you wont need much bedding in if any. Quote Link to comment Share on other sites More sharing options...
MrRalphMan Posted June 10, 2006 Share Posted June 10, 2006 Even if you don't replace the pad, you'll still need to take em out to replace the disk. Quote Link to comment Share on other sites More sharing options...
Ark Posted June 10, 2006 Author Share Posted June 10, 2006 OK, purchased: one 24" breaker bar (Biggest one in the store) Here's hoping! Quote Link to comment Share on other sites More sharing options...
SUPRALOOPY Posted June 10, 2006 Share Posted June 10, 2006 mind they don't shear. try puting the bar and socket on and appliying pressure then hit the centre of the bar with a hammer where it goes into the socket..as its only locktight holding the bolt in hope i'm not too late Quote Link to comment Share on other sites More sharing options...
Ark Posted June 10, 2006 Author Share Posted June 10, 2006 Talk about pissed off! No matter how much leverage I could get on the breaker bar, it's never going to move because the end's already on the ground or against the car! Plus the hot sun is making me sweaty, uncomfortable and even more annoyed. Fuck it, I'm giving it to a garage to do with their fancy ramps and stuff. Now I can't find a torque setting for putting the wheel back on. Anyone? Ta. Quote Link to comment Share on other sites More sharing options...
Ark Posted June 10, 2006 Author Share Posted June 10, 2006 By the way - thanks everyone for their help and advice. Starting to calm down a little now I'm sure you can see my irritation though - £800 worth of parts, more than £100 in new tools, and 5 hours of effort in the hot sun...and all I managed was taking one wheel off! How lame am I?? Quote Link to comment Share on other sites More sharing options...
Scooter Posted June 11, 2006 Share Posted June 11, 2006 Mate you are not lame.........this always happens with DIY stuff, you sometimes reach a point where you are thwarted by stubborn bolts or access issues etc etc..... give it another go with both front wheels off the ground and the steering turned to full lock. This may give you more range for your breaker bar to attack the caliper bolts. Quote Link to comment Share on other sites More sharing options...
Ark Posted June 11, 2006 Author Share Posted June 11, 2006 Ah - I hadn't thought of the steering lock thing - that may just do it. Not today though...I haven't worked up enough enthusiam yet. What's the best way to jack both front wheels then? (I only have one trolley jack). Is it safe to jack and axle-stand one wheel, then the other? Thanks for the vote of confidence too Quote Link to comment Share on other sites More sharing options...

Thanks for the vote of confidence too You could use the standard jack one side and the trolley the other and raise it each side a bit at a time and then ease back down onto the axle stands (this ensures no lateral load/movement to the 1st axle stand) i think with the wheel turned one caliper bolt is very easy to access the other you may need a small 2-3inch extension to let the breaker bar clear the caliper. good luck.

Need4Speed Posted June 11, 2006 Share Posted June 11, 2006 I use a Snap-on breaker bar and 17mm socket. No problem, and it's easy to see why good tools are worth the money - I bought them 10 years ago and they're still 100%. What's the best way to jack both front wheels then? (I only have one trolley jack). Is it safe to jack and axle-stand one wheel, then the other?Yes - I do this all the time. You should have no problem jacking one side enough to get the tyre off the ground, then stick in an axle stand and repeat on the other side.

carl0s Posted June 11, 2006 Share Posted June 11, 2006 I agree with turning the wheels. My long breaker bar only allows a small amount of movement in there, because as you say it's near the ground. I lift both front wheels in the air, and turn full-lock to get in there. You *will* be able to do it As for where to jack from, strangely I actually jack from the bit which is not a designated lifting point. Wierd, but the designated crossmember seems flimsy. I put the trolley jack in from behind one of the wheels (after driving onto a plank of wood) and up to the large cast crossmember. Once you've got the bar is a useful position, just give it a good hard thump down. Quote Link to comment Share on other sites More sharing options...
Need4Speed Posted June 11, 2006 Share Posted June 11, 2006 Full lock makes it all possible and I jack under the rear of the inboard wishbone mounts. Quote Link to comment Share on other sites More sharing options...
