Question on using larger brake booster
Question on using larger brake booster
(OP)
I asked this question in a car repair forum. No replies from there.
I have a 97 pickup, rear wheel drive, used as a spare vehicle. My wife's car (disk-disk) stops very quickly. To her, the pickup (disk-drum) doesn't want to stop. She refuses to drive it. My car is disk-drum, but stopping is not as bad as the pickup. I can replace the single diaphragm brake booster with a double diaphragm. What do I need to be aware of?
For your information, the pickup has ABS on all 4 wheels. The same model gets disk-disk and double diaphragm booster in 99 and later. Thank you.

RE: Question on using larger brake booster
If so then I would look at switching both the booster and the disks.
I don't think that the booster alone will help enough to make it worth while.

Doesn't double diaphragm double vacuum assistance?
RE: Question on using larger brake booster
The double diaphragm might increase the maximum available vacuum assistance, but the ratio between input force and output force (up to the maximum) is determined by a little valve and mechanism inside the workings. You also don't know whether the piston diameter inside the master cylinder is the same.
In short, "not enough information" and the information you need might not be readily available.
If you don't have excessive pedal travel right now (i.e. good firm pedal) and you can get a set of used later model calipers cheap, I'd swap those first and see what happens. Make sure you can't push the brake pedal to the floor before you drive it!

With regards to pads, a number of aftermarket manufacturers will make you a set of pads with the desired friction material if you provide them with the backing plate.

RE: Question on using larger brake booster
If the complaint is "it takes too much pedal pressure to stop the vehicle" and the pedal effort is typical for that vehicle, then the question is how best to reduce pedal effort.
Higher friction pads might be easiest. The double booster might also be fine - it helps her push harder on the pedal.
When you look at reviews for that vehicle, are there comments about brake effectiveness or pedal effort?
