Posidrive Posted June 22, 2015 Share Posted June 22, 2015 Intending to change the front disks and pads this weekend but feeling a touch twitching about getting the calipers off since I've heard a lot od stories about seized and suck bolts. I can cope with seized since will just mean biting the bullet and paying local garage to do it instead. But If the bolts are seized, how much leverage should I try applying before shearing the bolt is likely to be an issue? I suppose it is worth soaking in good penetrating oil first, any recommendations? Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted June 22, 2015 Share Posted June 22, 2015 The Brembo fronts will be very tight, however they won't shear, just apply even pressure at the correct angle using a large breaker bar and an impact socket. Quote Link to comment Share on other sites More sharing options...

Floydbax Posted June 23, 2015 Share Posted June 23, 2015 Honestly, it's a cinch. I'm dead slow at this kind of thing and it only took a couple of hours and was no trouble to do on the driveway with a trolley jack, breaker bar and a few other simple tools Quote Link to comment Share on other sites More sharing options...
Bundus Posted June 23, 2015 Share Posted June 23, 2015 I did my front calipers and pads recently and I agree its not a difficult job at all. It was a little time consuming as it was my first attempt at this job but next time will be a piece of cake. One little tip for tough bolts that I use is to attach the socket on a medium sized breaker bar then use a rubber mallet to hit the end of the bar (in the right direction of course). Sometimes this "impact" technique is enough to free any rust and move the bolt a few mm and makes it much easier to get off. I did of course coat the bolts in penetrating oil before I started so this definitely helps too. Also I found that a couple of standard G clamps are perfectly fine for pushing the pistons back into the caliper. So if you dont have a piston reset tool and you are in a pinch something like this works brilliantly.... http://www.screwfix.com/p/forge-steel-g-clamp-150mm/6624c Quote Link to comment Share on other sites More sharing options...
sharkmatt Posted June 23, 2015 Share Posted June 23, 2015 Also, a good tip is to try and tighten the bolt a small amount to crack the rust and then try backing it off. Quote Link to comment Share on other sites More sharing options...

When I use the rubber mallet technique I normally knock it once or twice in both directions and that's usually enough to get it free.
