How many threads are in a brake line nut?
Brake line nuts are more like hollow bolts and you measure the diameter of the threaded portion and the spacing of the threads. First we’ll cover some basic information on thread forms. In the U.S. inch system the standard fine thread 3/8″ diameter bolt has 24 threads per inch (tpi). This may be called SAE, UNF, or NF.
What kind of bolts hold the brake lines?
Nor are we talking about bleeder valves, bleed screws, banjo bolts or anything that holds on brake lines or lets you bleed the brakes. What we are talking about are what you see above — the bolts which hold calipers onto your car or truck.
Why are brake caliper bolts called bracket bolts?
Plain and simple. They’re often called “caliper bracket bolts” because they attach to the part of your caliper called the bracket, and hold it tight to the spindle or steering knuckle. Torque Talk… Now a word about torque, the twisting force that tightens a bolt. Because caliper bolts MUST stay on, they need a LOT of torque.
What kind of nut to use on Dia brake line?
M1-3 10mm x 1.0 common European/DIN nut with DIN flare (ISO/bubble) on 3/16″/4.75MM dia. brake line. If the end of the tubing looks like a button and the back side angle of the flare is 90 degrees it is the DIN flare. You must use a nut with a “lead” for the DIN flare.
How big are the bolts for disc brakes?
The bolts are too long by the 180 mount thickness (reasoning suggests 10mm too long… the radial difference between 160 and 180). I appreciate that, it just never crossed my mind as I’ve fitted loads of disc brakes and just removed the adapter. The instructions don’t say anything about 160mm not can I find bolts for sale.

Do you need to rethread the threads in a brake bolt?
If your bolt and bolt hole did not pass the “play” test above, you’ll need to rethread or clean the inner threads of the bolt holes before installation. To accomplish this, you’ll need a thread cleaner – commonly referred to as a thread chaser – that matches the exact thread as your spindle.
How do you turn a Torx screw brake disc?
Then use a hammer and hit the disc from behind. This sounds drastic but you do not need a lot of force in order to push the disc hole over the torx bolt. Then heat the bolt with a blow gun and use some mole grips to turn the bolt. You will need to really tighten the grips so that you require 2 hands to lock them.
