Strengths:    Power, Modulation, No squeals, Weight, Looks

Weaknesses:    spares are a harder to find than some other brands.
no reach adjust - can't have tooo small hands


Bottom Line:   
I've had them for over 2,5years and they still work w/o problems. I used to downhill with them for the first two months but the levers/master cylinder are not made to take that kind of continous crashes.
For riding trails they are defenetly adequate. Power is good and they can take an occational crash.
I recomend them for enduro, but if you don't care to much about weight get the 4Racing FR/DH model.

4/5 in value cus i think biking products cost to much (but they have still better value compared to other brands).

5/5 overall cus haven't had any problems when i've used them as they are intended to.

Strengths:    Non that I can think of. They suck.

Weaknesses:    I've had problems with them from the start. Dealers have a hard time getting in touch with a rep. Getting parts is like pulling teeth. Most shops don't have any parts in stock, including pads.

Bottom Line:   
Don't buy a bike with them on it and don't by them
thinking that they are a good upgrade. On two occasions my bike was in the shop for three weeks waiting for parts.
I just dumped them and sent the box of parts to Formula with a nasty note. I can't believe they can stay in business and that bike companies would even consider using them on their high end bikes. I just installed the Avid CPS Mechanical Disc Brakes and I love them.

Strengths:    Quiet

Weaknesses:    Constant problems, fix it and another one shows up.

Bottom Line:   
Don't touch this even if you get it for FREE. Initially I thought I had gotten a great deal, in the end this thing has cost me so much in spare parts, time and frustration. I just had to come back after about a year and review the brakes again. Basically they suck !! The last straw was having them lock up on me 1 mile into a 6 mile downhill. Today, the disc cracked after they got warped mid ride and I tried to true them.....another ride f'ed up.

I am definitely going with Hope Mono M4's or Avid Juicy's now.

Stay away from these.

Strengths:    Strong, easily modulated power. No squeal.

Weaknesses:    Maintainence can be an issue.

Bottom Line:   
I have found that for my application these brakes are good. I had initial trouble setting up the calipers due to the odd offset on my Xyclone wheels but once they were on and broken in I have not had to alter the setup.
I have also had one maintainence issue where one of the membranes in the lever was perforated. It then proved nearly impossible to replace it without leakage. I ended up having to replace the whole lever.
Onto the performance...
I am really impressed with the performance of these brakes. When setting my bike up I decided to take the weight penalty and go for bigger brakes and I am glad I did.
While I would be loath to tackle a big downhill course with these brakes they have taken all of the racing and trail riding I have thrown at them with ease. They are very powerful and have great modulation. When racing it is a great feeling to see the guy in front of you and be able to take a couple of metres out of him at each hard corner. Even if the cost a little weight I think this makes up for it.
Some people have had big maintainence issues with these brakes so maybe I have been lucky. I feel that disc brakes are probably one of the most fiddly bits on a mountain bike and hydralicc discs are the worst of all. If they work they work well but if they do not you can be chasing around for days trying to work out why.
If you are looking for fairly light, powerful brakes then these brakes may fit the bill.

Strengths:    they look nice and appear to be well made

Weaknesses:    they squeal they have air in them they are underpowered they are supposed to break in within 100 cycles fat chanch the tech support is awful i asked for certain fittings and got nowhere it consequently wound up that i sent them back to thorsten khs had a good customer satisfaction policy thank goodness thank you erica

Bottom Line:

Strengths:    NONE

Weaknesses:    The Product itsself is a weakness

Bottom Line:   
These Formulas don't need to be called brakes. They don't stop you, why call them brakes ? They leak, squeal and don't stop. Have I mentioned they don't stop ? They worked for 1 month and that was the end of it.

Never buying Formulas again. Now ordered Hopes coz my friends all like em alot and they keep working.
I hope the Formula factory burns to the ground !

Too bad the rating can not go below zero

Strengths:    Great Power - the quad piston 8" disc really has HEAPS of power when it is working correctly!

Weaknesses:    LEAKING!!!!!
The brake line permanently had air in it!
No back-up service and very hard to get pads and other parts. Very hard to bleed!


Bottom Line:   
Really not a good brake - after every ride it had air in the line.
I would never buy another Formula product again!
Shimano Deore hydraulic disc was the best performing above hayes!

Strengths:    Weight, Silent...not much squeeling.

Weaknesses:    Leaks constantly, parts very difficult to find locally, support not good.

Bottom Line:   
Technical support awful. My brakeset came with the 160mm disc and the adaptor for a 185mm disc. The company would not change to the proper adapter and I had to buy a new one. I have tried to bleed the brakes and it constantly goes flat. So I haul my bike on a mtn. bike vacation and sure enough, it dies again. So I am forced to send it to the bike shop where they charge me $25 to bleed only the rear brakes. It feels great initially and I am happy that they did it better than I did, but by the end of the first ride.....it is dead again.

Try going to any bike shop and look for brake pads....you'll find Avids, Hayes, maybe Magura....but no Formulas.

I may just change mine soon. I have always had good luck with Maguras, the Martha looks good.

Strengths:    Power, modulation, light

Weaknesses:    LEAKING, LEAKING, LEAKING. Stupid tiny lever.

Bottom Line:   
I've tried to pull out air but it's impossible. Super power lasts only one downhill. Then air gets inside and you have 30% of power and they leak through reservoir. I've changed DOT fluid more times and it have not helped. If they work they are great. But it is very short time. I've returned them and now I want to buy Hope M4.

Date Reviewed: February 13, 2003

Strengths:    Price, weight, power, no squeals

Weaknesses:    Lever may be fragile, spares, no shims included.

Bottom Line:   
My first foray into disc brakes. They fitted relatively easily, the shimming took some time and I had to visit my LBS for a selection of shims (they don't come with the kit). They run a fairly big gap between pads and disc and so the lever movement is large but it suits me. They're a pimpy gold anodised finish, looks nice. Performance so far is outstanding but I've nothing to compare it against except the Arch Rival Vs. They bedded in after an hour or so. I ride trails and they cope admirably with this. I'd give them five but let's see how they work out. Oh and so far, they don't squeal like Hopes!
