Flare nut wrenches are just small wrenches, usually 5/16 or similar with a slot to pass over the pipe.
It's a small wrench with an opening at the end so it can slip over brake and fuel lines. The head is a kind of C shape.
A 35mm wrench....
An adjustable wrench is used when you don't know the exact size of the nut you will be turning
Do up or undo a nut where a ring wrench or socket might otherwise not fit.
To calculate wrench size you measure across the flat surfaces of the nut or bolt, then pick a wrench marked with that size. Be careful, there are metric and SAE nuts and bolts and some wrenches are close but not right. -For instance you should not use a 1/2" wrench on a 12 mm nut. -It may look right, but will round the edges of the nut.
Yes, a torque wrench is a precision instrument (or tool). -If damaged or even slightly bent it may give incorrect readings. It should always be kept in a separate case or box, nut just flung in a toolbox with over heavy tools (as I sometimes see)
An open end wrench.
A flare wrench, also known as a flare-nut wrench, tube wrench or line wrench is used for gripping the nuts on the ends of tubes (like automotive brake lines and household plumbing). It is similar to a box-end wrench but, instead of encircling the nut completely, it has a narrow opening just wide enough to allow the wrench to fit over the tube. This allows for maximum contact on plumbing nuts, which are typically softer metals and therefore more prone to damage from open-ended wrenches. See images of flare nut wrenches by searching google and see what purchase links pop up. Cheers
A wrench is a tool used to turn a bolt or nut.
A flare wrench is the proper tool. Looks like a box end wrench with just a slot cut through the end to go over the line. Grips on 3 sides of the nut so that hopefully it doesn't round off the sides of the nut. Some WD-40 or similar wouldn't hurt and a hammer to give the wrench a sharp tap to break contact on the nut. Vice grips if you have to.
Use a flare nut wrench, and hold whatever it is screwed into from turning to prevent damaging the tubing
Your question needs some clarification. If you meant to say how do you replace the front/rear flexible brake hoses (assuming you have rear disc) or how do you replace all of the brake lines on my Accord that would greatly help direct a more direct response. You should have specific hand tool before changing your brake lines, and that is a flare nut wrench. I have a 10mm and 12mm flare nut wrench that works well. This wrench if thicker than a standard wrench and one side is approximately 75% closed (like a box end wrench) to allow for more contact area and reduce stripping the flare nut. There are also clips that hold the line to a bracket where the 'hard' & 'flexible' lines connect. Leave this in-place until you have loosened the connector (and install the clip) before you tighten the connector
A combination wrench is a tool that has two ends used to loosen or tighten a nut or bolt. One end typically has the appearance of a U or open jaw, the other end is a close circle with grooves that operates similar to a socket wrench.
No, totally different. A wrench is for turning nuts and has jaws to fit different nut sizes. A crimping tool is a kind of plier for tightening special rings.
You need an impact wrench
torque wrench
Barrel nut wrench available through Brownells.
No, just loosen the nut on the back with a 15mm wrench.No, just loosen the nut on the back with a 15mm wrench.
