I have no tech.knowlege but my brakes are what I would call soft, as opposed to my rover car, which are more postive. I have a C15 1999 model , my previous C15 was an 1989 the brakes were the same, you really needed to brake early! Joan

Hi rhydian, ours is a 92 c15 and yes the brakes are a bit soft compared with our car. As lunnie said you have to brake early and press hard. If you are still in doubt ask Ant. He is the expert.

Hi Rhydian. C15 brakes can be interesting! They do need the servo to be working well and for that to work well you need a good vacuum from the pump ( driven by belts or diect from cam shaft). If you pump up the brake pedal and while pushing down on it you start the engine your foot should sink as the servo opperates. If your foot doesn't sink you need to get either the servo or vacuum pump sorted ( vacuum pump is more likely to be the culprit). The rear brake valve compensator can also be adjusted to make the rear brakes help out a bit. Ant

Hi rhydian
"C15 brakes can be interesting" stated by Ant, and he's not kidding.
When I first got mine I thought there was something very wrong with them, servo and pump were working OK, changed all the brake pipes, because they were rusty.
Then came a big problem, when I tried to bleed the system both front bleed nipples, being corroded into the caliper,snapped off, so new calipers put on.
Front discs worn a bit and seemed OK but I replaced them any way, pads only half worn but replaced them too, rear drums OK ,shoes, as front only half worn, but replaced also.
When all done and about 100 miles or so later they were better, but still, in my opinion, not good, and to my surprise it past the next MOT with no problems.
But I was still not happy with the braking system, next to look at was the rear brake valve compensator. I got a friend to operate the brakes while I looked at the rear brake valve compensator in operation, I didn't know how it worked, but it seemed to me that it wasn't doing what it should properly. The lever, which is under spring tension, came out when the brakes were applied but seemed to settle back, this seemed to me as not being right, so I put a new one on. And yes, there was a great improvement, and I don't think I can get them any better than they are now.
They are still the worst brakes of any "modern" vehicle I have ever driven and I always leave plenty of space between me and the vehicle in front.
The only way I can see to get them better is to put in a larger servo, larger discs , and calipers with larger pistons, but I think none of this is possible, and if it is the expense would be prohibitive.
So drive with care.
Sorry its a bit long winded and I hope it is of some use.
Martin
P.S. You may already know this but just in case, don't forget that the new pads have to bed in before they become fully effective, and when bleeding the system it is always better to do them in the correct order, and according to Mr. Haynes the sequence is ----- 1 FOS, 2 FNS, 3 ROS, 4 RNS
