Disc Brakes
- Thread starter martin maltas
- Start date
Been thinking again!! now I remember reading a list here of all the different model cars with rims that fit (or should )and thought do any of these have a hat type vented disc on the front the hat width ( depth ) would have to be similar to the drum width or less.Now if the rim fits the p.c.d and stud pattern there should be no reason that this disc wont fit only needing a mounting plate to hold the caliper.
Next would anyone know the track measurements front and rear.
Also what is the widest offset rim that can be fitted before the steering lock and body get fowled by the tyre, and whats the widest rim anyone has fitted to the front and rear without any thing rubbing (front inner wish bones and outer body) rear before difficulty in removing and rubbing springs or body , what tyre width did you have on the rim also.
had some success with some hat discs but the large p.c.d centre is giving me grief , may have to go the make a hub route ,yet , but still thinking.
these humber things are not easy to find over here , even the clubs were holding there parts close and firm .

Rover sd1 has the same pcd and vented discs, although they are not that big in diameter
front track is 47.75"
rear track is 55.5"
"you were only supposed to blow the bloody SLIDING doors off"

It's been a while, so I'm curious whether anybody here has made any further progress on a front disk conversion for the Commer ?

I've found a '67 Humber Hawk being broken which has the front disks and rear axle available 
Opening price is a bit steep but before I think about starting any haggling,
a) Would these likely to be the correct sort (or what do I need to look for to confirm - awaiting pics)
b) Availability of consumables, ie. pads, discs & caliper overhauling etc. Martin, have you had any luck in sourcing these ?
Might just be what a Commer Holbay needs

Humber Club is best source, but they are difficult to get

Disc brakes are good but drums set up properly are well up to the job, you can lock the wheels up so how much more braking do you want:I The addition of a servo is a definite plus (and a cheaper option)
The main advantage of discs over drums is that there is less fade with repeated braking (discs cool down quicker) and adjustment is automatic. With the advanced planning needed to drive a Commer I guess fade is something that is very unlikely and regular checks need to be done on the rest of the hubs/steering anyway. Shoot me down but I reckon drums + servo is the best option. Don't forget you will also need to transfer the handbrake to the rear wheels if you fit discs.

I don't know about anyone else, but I'm OK with my drums. For the performance of the Commer, I think they're well up to the job. The difference between a good condition brake setup and a bad one is massive. It's worth checking that all slaves and master are operating cleanly, drums are round and not scored, flexi hoses aren't old and perished (they swell on the inside and massively increase the pedal pressure required) and the brake fluid is fresh.... before going the disc route.
A servo is a good idea as Panky says, although I have heard they're not as suitable for drum braked cars as drums tend to grab (resulting in potential wheel lock up) whereas discs are more progressive.

Fade is the main issue with drums, actual braking efficiency is fine in my experience but when towing a heavy trailer-tent with my Imp downhill stretches were interesting to say the least. It is for this reason that I will eventually get around to fitting the disc kit I bought for it about 2-3 yrs ago. As I intend to use Peggy to tow the Imp (A-frame) I may need to upgrade to discs for her as well. We'll see how she copes first.
If I told you I was a pathological liar, would you believe me?
Peggy's got an MOT !!! (not a lie)

Me & Admin have got on fine with a remote servo set-up. Seems to make the brakes more progressive and certainly enhances the feel.
I have however boiled my fluid on long downhills and would like discs to overcome this.

Its a good idea to get rid of all the rubber hoses for goodridge stainless braided ones, this will improve things noticably as the fluid pressure will get to the wheel cylinders instead of swelling the hoses.
servo boost ratio is something to pay attention too, too high and the brakes will grab
using the humber discs could be a backward step in that they are probably quite small and have less total braking area than drums. and the calipers are less than desirable, and then there is the unobtainability factor.
if you want discs then try to find something more modern and easily obtainable and vented and with some decent calipers.
When i do the Dodgeyslyder v8 i shall be looking at the donor Rover sd1 vented discs and 4 pot calipers, the same pcd so its a good starting point

With the difficulty of service items the Humber swap sadly doesn't seem a sensible solution for us - if anybody is interested in my contact just PM me (don't expect a bargain though).
Our hill braking incident was down to some master cylinder issues, now sorted thankfully !
As the servo would be good for discs too, adding one is a no brainer and if get our drums fully overhauled maybe they'll will be fine - it's not as if we've on a V8 (in our Commer at least)

Someone on ebay is advertising pads for the Humber brakes, £65 though[B)]

Rather rusty but possibly reconditionable and quite cheap, from a Super Snipe - can anybody tell whether these have the required bits to mate to the Commer ?
