New to bike repair and have a caliper selection question.

[jumpin_jumpin]

xposting this to a few forums as I truly don't know where to start!

I come from a car repair background and am trying to learn more about bikes. I have a bianchi I use to commute, and an ol' fuji single speed I'm using as a learner.

Just toyed around on the brakes a minute and one part broke (old). Yay! New parts! But how do I know which calipers to get? The options are overwhelming and endless.

SORRY for the sloppy links but these are the ones I'm looking at. Cheaper side since this is just for learning.

People dont like opening links from new members.

If your a car mechanic it should be obvious how to select the right brake.

Post a pic

You'd be better looking at one or two of the online cycle stores - like WIggle/Chain Reaction, SJS, Tredz, Merlin et al for more specific details - prices unlikely to more than Amazon - and when you've worked out what you want have a look on ebay for Buy it now offers -- very often stonking deals to be had.

It will be hard to fit a modern rear brake to that bike, most fit with a sleeve nut these days, you can use a front caliper on the rear though (they're identical apart from a longer bolt) and use the old nut to retain it.

A picture of the broken bit might help.

 

[brucers]

Take it into a bike shop and see what they say.

 

[Cycleops]

As pointed out modern brakes won't fit. Best to take it to your local bike shop and they should have something suitable. Might be a good idea to replace the cables while you're at it.

 

[Globalti]

Have a look around for a bike jumble locally. You'll find loads of old brakes like that going for a song.

 

[Cycleops]

Alternatively post a wanted ad on here, most of us especially the vintage fans will have one laying around they'd be happy to sell you for little. @biggs682 springs to mind!

Edit; looking at your pic a little closer in fact you don't even need a complete caliper, just the guide the cable sits in. You've sheared off its mounting.

 

[Globalti]

Any decent shop mechanic would have one of those knocking around in the big box of bits.

 

[biggs682]

Thanks @Cycleops

@jumpin_jumpin i would wander into a local bike shop as like @Globalti says a good old fashion shop should have one of those if you don't turn up one then by all means get in touch and i can see if i have a spare one but sjs sell them

It's not the retaining cable bolt but the guide and adjuster as shown here:

But as you say LBS should have them.

Is the OP in the US given all the links are to amazon.com? may have an impact on UK based retailer accessibility

 

[jumpin_jumpin]

Thanks, everyone! Didn't realize I had a 'vintage' set up going on. I appreciate the pointers (except the 'it should be obvious'). Interesting to read that a front caliper could technically be used.
The bike will be for riding again some day but for now it's for tearing apart and learning! I'll ride the bianchi.

 

[raleighnut]

This shows the 2 types of caliper mounting, as can be seen in the 'Recessed Mounting' picture the retaining bolt isn't long enough to go through the brake 'bridge' on the frame (and then get a nut on) and is held on by an 8mm 'sleeve nut' with hex key fitting in the end, front brakes of this type are identical apart from a longer bolt.

BTW it's not a vintage brake caliper it's a traditional one.
