what size caliper bolts are on the rear of an sri?

[jasper5]

the rears are 7mm allen on the top and a 16mm hex spanner or socket on the bottom and there is no caliper carrier on the rear as they bolt to the hub.

mine was a 6 for some reaosn on the top bolt, annoying as i went and bought a 7mm caliper key, why is mine a 6 and everyone on here says 7? i used a torx bit in the end

Well, I said sometimes they are 6mm.

The front caliper frame bolts can be VERY tight, you need a breaker bar or an extended ratchet handle or T bar.

i breaker bar wont do any more then what ive already got, what im using is too big, got the 1/2 wrench and then an inch long torx bit, just twists, its a t55 x 75mm, i dunno why its so long its stupid, cant get enough torque on it

[jason1987]

im using one of these http://coilspringcompressor.co.uk/image ... reaker.jpg

will a breaker bar be any better?

[jason1987]

im gonna have to try a blow torch

Before you try to undo bolts like these, give them a good clean hit with a hammer, without damaging obviously.
The shock will break any lock tight or rust just enough to make that first turn a lot easier and reduce the chance or rounding.
After the hammer shock treatment, insert your hex / torx bit and give that a couple of short sharp hits to make sure its seated properly into the head.
The best device for applying good torque is this http://www.machinemart.co.uk/shop/produ ... reaker-bar its cheap and strong and has the advantage of good leverage and most importantly the angle of the socket is 90 degrees to the bolt, where as your whelbrace type bar will be more inclined to round stuff off due to the angle.
Always invest in good quality tools. MAchine mart do a really good range of gear, always go for the "professional" range as it comes with lifetime guarantee which you need with the torx and hex bits.
Obviously you cant beat Snap On but they are premium prices.

even tho my torx bit is about an inch long? so better to buy breaker then blow torch? i did hit it with a hammer etc and still wont budge

[TRAVIS BICKLE]

Are you using a good heavy hammer? not one of these little claw hammers for putting tacks in
Yes even though its a small bit the breaker bar is still the best, you get so much more torque with it being 90 degrees on. using a blow torch wont really help much, they cant get hot enough.

[jason1987]

na not a real heavy hammer, and na i mean my torx bit is long, so with the wheel brace thing im using it just twists, isnt a flat fit, im hoping the breaker will be better

[jason1987]

Those wheel brace things are hopeless, they aren't set at 90 degrees so you lose all the torque.

A 2 foot breaker bar will be better or somehow bend the wheel brace to 90 degrees.

Or, as I said earlier, a T bar from a socket set with a pipe on the end will help.

A shorter torx bit will help too.

tryin to think if theres room under a wheel arch for a breaker bar?

Get the shortest torx bit you can too. one hand holding the knuckle of the breaker bar keeping it nice and straight and the other applying some starting pressure, then give it some big pressure. if it has started rounding already you would be better off beating the next size up torx bit in before you try anything else.

Also if room is tight, jack the car up as high as possible so you have more room underneath.

theres a little rubber cap on my caliper but i cant remember what i do with it lol, i thought it might be where the wear indicator wire feeds through but it doesnt look big enough, whats it for?

Without looking i cant remember, its not the cap for the bleed nipple is it?

[jason1987]

na im sure i took it off for the sensor wires, but then the new ones are plugs on one end and the other end is attached to caliper, so not sure.
