The Gunson 77152 Brake Adjusting Wrench is a specialized tool designed for adjusting brakes on classic cars, including the Mini. This durable wrench features a 1/4 inch square and a 5/16 inch square, crafted from Chrome Vanadium, which provides strength and longevity for automotive tasks. Consumer feedback indicates some challenges with this tool, particularly regarding its usability. One user noted, "If it’s too hard to turn, it’s probably seizing up," highlighting concerns about the tool being difficult to operate by hand. Additionally, there are warnings against using an impact gun, as it may lead to damage, reflecting a need for careful handling when using this wrench. Based on the feedback, while the Gunson 77152 Brake Adjusting Wrench is a reliable tool for its intended purpose, potential buyers should be aware of the operational challenges.

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.
Common techniques for brake bleeding
This was actually VERY easy.
I thought it was a lot easier to do all 4 at once.
I always go a few extra steps.
A pressure bleed and fluid flush would be best if the fluid is brown.

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Different brake jobs may require different approaches
my pads ware was majority of the way even but now I have a service light on and not sure what to do any ideas.
You need the tool that rotates while it compresses.
Y'all don't just c-clamp that bitch and hope for the best up at the master cylinder?
What they are really saying is, "don't scratch the pistons!!"
Common methods used for brake bleeding
Has anyone actually made this with a master cylinder cap and a Schrader valve w/ JB Weld and hooked up an air chuck with the compressor regulator at 10 psi to bleed brakes?
It doesn’t leak at all, and is the best pressure bleeding system I’ve ever used.
This is a very common way of bleeding brakes.
Brake fluid absorbs water over time
Brake fluid isn’t mileage based, it is time based.
Brake fluid loves water.
Brake fluid change is time-based, not mileage-based
I can feel the difference between old and new fluid when you start really using the brakes.
Testing brake gain settings based on feel is common practice
Test several times until you get a feel for your trailer and the loads you typically carry.
I basically shoot for the braking feel and performance to be the same with a load or without.
If the trailer is pushing you through an intersection it’s too low.
My grandpa always told me just set them until you can feel the trailer tug a little bit and your good.

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Issue with caliper piston retraction is common
Rear Brake Caliper Piston Won't Retract Even With the Correct Tool.
Who rebuilds calipers. Buy a new one.
Interesting tools to reset this brake caliper.
you go get a rubber brake hose because the one on the car is collapsed inside.
Different experiences with changing brake fluid
Used to get my dad on the brake pedal 'Next one down dad'.
But if you were doing all of them, fluid makes sense.
