Getting the brakes working perfectly on every bike I come across is sort of a holy grail for me.  Maybe it's because I like to bike fast, but weigh about 200 lbs so run into brake problems more often than others, maybe it's the winter biking where your brakes really have to be reliable, I dunno.

I've become pretty adept at toeing in brake pads to various angles, swapping out brake pads, filing them down when they get glazed, digging bits of rim out of them, keeping the rims as clean and oil free as humanly possible.  A few days ago I installed a big aluminum horseshoe on my bike with v-brakes:



It's called a brake booster.  You take out the bolts that hold your brakes on, put in a spacer and some washers, then screw this on the front.  It is the best 5$ I've ever spent on a bike.  This thing keeps the pivots that your brakes are on from flexing (which apparently they do when braking).  It has two effects:
- Your brakes just feel better.  They're less mushy, and easier to modulate.  They seem to be more powerful as well.
- I've tried two different types of brake pads with them, and about several different amounts of toe in (from about 2 mm to parallel with the rim).  These things eliminate brake squeal.  I put on a set of brake pads that previously squealed so badly it was impossible to use them . . . whisper quiet.  I spent all winter last year adjusting these pads to try and get rid of the squeal (in my freezing cold garage) with no luck.

I'm going to stick a booster on my road bike with cantilever brakes to see if it gets rid of the shudder that I sometimes experience under hard braking in the front.  If you have v-brakes I would recommend these things 100%.

I fixed this problem with a front hub that is a drum-brake & dynamo.  Reliable brakes + reliable lighting.  :^)

ETA:  It was more than $5 though ...

I'd be curious to see pics of it mounted to your bike, if you can post them.

Me too. This sounds very interesting.

Yup, would love to see a pic.

A fork mount cable hanger is far more likely to fix this.

Pretty "meh" on brake boosters in general. No offense, but you really oughtn't to need them if you're properly set up with decent pads, even in winter, even if you bike fast, even if you are 200#.

Through a bit of google searching (Since I had never seen one of these before) it seems that on cheap frames this may or may not help a fair bit.

I also found this, which seemed like a very mustachinan take on it! (The photo includes a caption below)

I didn't take a pic of my bike, but it looks pretty much like this:



It's just a chunk of metal that sits in front of the brakes on spacers.

It may not make a difference if you have an expensive fork, or if your bike has great quality v-brakes.  Before installing the brake booster I couldn't get the Kool Stop black pads that I'd been using for about a year to stop squealing when dry, so I changed them out for some brand new Swiss Stop GHP pads.  I took both sets of pads in to the guys at the bike shop and they couldn't get the pads to be quiet either.  They tried some cheap tektro brake pads which ended up being a bit quieter, but also much less powerful.  One of the guys there suggested I try a brake booster.

I guess it's possible that neither I, nor the guys in the bike store know what we're doing as far as toeing in brake pads.  Even if it hadn't completely solved the squealing issue though, I'd keep the booster on because the braking is noticeably more solid.  Especially when I'm pulling my son around in his bike trailer this is very noticeable.  What do you not like about them?
